27 <title>About TTF and OTF fonts</title>
28
29 <para>
30 Originally, Xorg provided only bitmap fonts. Later, some scalable
31 Type1 fonts were added, but the desktop world moved on to using TrueType
32 and Open Type fonts. To support these, Xorg uses Xft, the X FreeType
33 interface library.
34 </para>
35
36 <para>
37 These fonts can provide hints, which <application>fontconfig</application>
38 uses to adjust them for maximum readability on computer monitors. On linux
39 you should always prefer the hinted versions, if available (in general the
40 latin, cyrillic and greek alphabets can use hints, most other writing
41 systems do not use hinting).
42 </para>
43
44 <para>
45 A few fonts are provided as collections (TTC or OTC) where font data
46 is shared between different fonts, thus saving disk space. Treat these in
47 exactly the same way as individual TTF or OTF files.
48 </para>
49
50 <para>
51 If a font provides both TTF and OTF forms, prefer the OTF form in
52 linux, it may provide more features for programs which know how to use them
53 (such as xelatex).
54 </para>
55
56 <para>
57 For some scripts <application>pango</application> is required to
58 render things correctly, either by selecting different glyph forms, or by
59 combining glyphs - in both cases, according to the context. This applies
60 particularly to arabic and indic scripts.
61 </para>
62
63 <para>
64 Standard scalable fonts that come with <application>X</application>
65 provide very poor Unicode coverage. You may notice in applications that
66 use <application>Xft</application> that some characters appear as a box
67 with four binary digits inside. In this case, a font with the
68 required glyphs has not been found. Other times, applications that
69 don't use other font families by default and don't accept substitutions
70 from <application>Fontconfig</application> will display blank lines when
71 the default font doesn't cover the orthography of the user's language.
72 </para>
73
74 <para>
75 The fonts available to a program are those which were present when
76 it was started, so if you add an extra font and wish to use it in a program
77 which is currently running, then you will have to close and restart that
78 program.
79 </para>
80
81 <para>
82 Some people are happy to have dozens, or even hundreds, of font files
83 available, but if you ever wish to select a specific font in a desktop
84 application (for example in a word processor) then scrolling through a lot of
85 fonts to find the right one is slow and awkward - fewer is better. So, for
86 some font packages you might decide to install only one of the fonts - but
87 nevertheless install the different variants (italic, bold, etc) as these are
88 all variations for the same font name.
89 </para>
90
91 <para>
92 In the past, everybody recommended running <command>fc-cache</command>
93 as the <systemitem class="username">root</systemitem> user after installing
94 or removing fonts, but this is no-longer necessary on linux,
95 <application>fontconfig</application> will do it automatically if needed and
96 if its caches are more than 30 seconds old. But if you add a font and want to
97 immediately use it then you can run that command (as a normal user).

101 There are several references below to CJK characters. This stands for
102 Chinese, Japanese and Korean, although modern Korean is now almost all
103 written using the phonetic Hangul glyphs (it used to sometimes use Hanja
104 glyphs which are similar to Chinese and Japanese). Unicode decided to go
105 for <ulink
106 url="https://en.wikipedia.org/wiki/Han_unification">Han Unification</ulink>
107 and to map some Chinese and Japanese glyphs to the same codepoints. This
108 was very unpopular in Japan, and the result is that different fonts will
109 render some codepoints in quite different shapes. In addition, Simplified
110 Chinese will sometimes use the same codepoint as Traditional Chinese but
111 will show it differently, somewhat analagous to the different shapes used
112 for the letters 'a' and 'g' in English (single-storey and two-storey),
113 except that in a language context one will look "wrong" rather than just
114 "different".
115 </para>
116
117 <para>
118 Unlike most other packages in this book, the BLFS editors do not
119 monitor the versions of the fonts on this page - once a font is good enough
120 for general use, the typical additions in a new version are minor (e.g. new
121 currency symbols, or glyphs not for a modern language, such as emojis or
122 playing cards). Therefore, none of these fonts show version or md5
123 information.
124 </para>
125
126 <para>
127 The list below will not provide complete Unicode coverage.
128 Unicode is updated every year, and most additions are now for historic
129 writing systems. For almost-complete coverage you can install <xref
130 linkend="noto-fonts"/> (about 180 fonts when last checked) but that
131 number of fonts makes it <emphasis>much</emphasis> less convenient to
132 select a specific font in a document, and most people will regard many
133 of them as a waste of space. We used to recommend the <ulink
134 url="http://unifont.org/fontguide/">Unicode Font Guide</ulink>, but that
135 has not been updated since 2008 and many of its links are dead.
136 </para>
137
138 <para>
139 Rendered examples of most of these fonts, and many others, with
140 details of what languages they cover, some examples of latin fonts with
141 the same metrics (listed as "Substitute latin fonts") and various files
142 of dummy text to compare fonts of similar types, can be found at this
143 <ulink url="http://zarniwhoop.uk/ttf-otf-notes.html#examples">
144 font comparison</ulink> page. That site also covers other current
145 writing systems.
146 </para>
147
148 <para>
149 Fonts are often supplied in zip files, requiring <xref linkend="unzip"/>
150 to list and extract them, but even if the current release is a tarball
151 you should still check to see if it will create a directory (scatterring
152 the contents of a zipfile or tarball across the current directory can be
153 very messy, and a few fonts create odd __MACOSX/ directories. In addition,
154 many fonts are supplied with permissions which do not let 'other' read
155 them - if a font is to be installed for system-wide use, any directories
156 must be mode 755 and all the files mode 644, so change them if necessary.
157 If you forget, the root user may be able to see a particular font in
158 <command>fc-list</command> but a normal user will not.
159 </para>
160
161 <para>
162 As a font installation example, consider the installation of the
163 <xref linkend="dejavu-fonts"/>. In this particular package, the TTF files
164 are in a subdirectory. From the unpacked source directory, run the
165 following commands as the <systemitem class="username">root</systemitem>
166 user:

168

172
173 <para>
174 If you wish, you can also install any licenses or other documentation,
175 either alongside the font or in a corresponding directory under
176 <filename class="directory">/usr/share/doc/</filename>.
177 </para>
178
179 <para>
180 A few fonts ship with source as well as with the completed TTF or OTF
181 file(s). Unless you intend to modify the font, and have the correct tools
182 (sometimes <xref linkend="fontforge"/>, but often commercial tools), the
183 source will provide no benefit, so do not install it. One or two fonts even
184 ship with Web Open Font Format (WOFF) files - useful if you run a webserver
185 and want to use that font on it, but not useful for desktops.
186 </para>
187
188 <para>
189 To provide greater Unicode coverage, you are recommended to install
190 some of the following fonts, depending on what webistes and languages you
191 wish to read. The next part of this page details some fonts which cover
192 at least latin alphabets, the final part deals with come CJK issues.

266 minority languages, but the glyphs are comparatively small (unlike DejaVu
267 fonts which are comparatively large) and rather light weight ("less black"
268 when black on white is used) which means that in some contexts such as
269 terminals they are not visually pleasing, for example when most other

308
309 <para>The <ulink url="http://corefonts.sourceforge.net/">Microsoft Core
310 fonts</ulink> date from 2002. They were supplied with old versions of
311 Microsoft Windows and were apparently made available for general use.
312 You can extract them from the 'exe' files using
313 <application>bsd-tar</application> from <xref linkend="libarchive"/>.
314 Be sure to read the license before using them. At one time some of
315 these fonts (particularly Arial, Times New Roman, and to a lesser
316 extent Courier New) were widely specified on web pages. The full set
317 contains Andale Mono, Arial, Arial Black, Comic Sans MS, Courier
318 New, Georgia, Impact, Times New Roman, Trebuchet MS, Verdana and
319 Webdings.

323 Please note that if you only want to use a font with the same metrics
324 (character size, etc) as Arial, Courier New, or Times New Roman you can
325 use the libre Liberation Fonts (above), and similarly you can replace
326 Georgia with Gelasio.
327 </para>
328
329 <para>
330 Although many old posts recommend installing these fonts for
331 better-looking output, there are more recent posts that these are ugly

350 The <ulink
351 url="https://www.google.com/get/noto/">Noto fonts</ulink> ('No Tofu', i.e.
352 avoiding boxes with dots [hex digits] when a glyph cannot be found) is a
353 set of fonts which aim to cover <emphasis>every glyph in unicode, no
354 matter how obscure</emphasis>. These fonts, or at least the Sans Serif
355 fonts, are used by KF5 (initially only for gtk applications). If you want
356 to cover historic languages, you can download all the fonts by clicking
357 on the link at the top of that page.
358 </para>
359
360 <para>
361 People using languages written in Latin, Greek or Cyrillic alphabets need
362 only install Noto Sans itself, and perhaps Noto Sans Symbols for currency
363 symbols. For more details on the CJK fonts see <xref
364 linkend="NotoSansCJK"/> below. There are also separate fonts for every
365 other current writing system, but these too will also require Noto Sans
366 (or Noto Serif) and perhaps Noto Symbols.
367 </para>
368
369 <para>
370 However, you should be aware that <application>fontconfig</application>
371 knows nothing about Noto fonts. The 'Noto Sans Something' fonts are each
372 treated as separate fonts (and for Arabic there is not a specifically Sans
373 name), so if you have other fonts installed then the choice of which font
374 to use for missing glyphs where 'Noto Sans' is specified will be random,
375 except that Sans fonts will be preferred over <emphasis>known</emphasis>
376 Serif and Monospace fonts because Sans is the fallback for unknown fonts.

388 When KDE Frameworks 5 was first released, it used the <ulink

390 which were designed for integrated use with the KDE desktop. Those fonts
391 are no-longer actively maintained, so KDE made a decision to switch to

394 </para>
395
396 <para>
397 Originally these fonts were only supplied as source, needing <xref

399 files. But for a while the source has also included the prepared TTF.
400 The only unusual feature is that each TTF file is in its own subdirectory
401 (<filename class="directory">oxygen-fonts/{*-?00}/</filename>) with the
402 source in further subdirectories. You could just install the whole

410 <para>
411 As indicated earlier, usage of a combination of Chinese, Japanese
412 and Korean can be tricky - each font only covers a subset of the available
413 codepoints, the preferred shapes of the glyphs can differ between the
414 languages, and many of the CJK fonts do not actually support modern
415 Korean.
416 </para>
417
418 <para>

425 Although Unicode has been extended to allow a very large number of CJK
426 codepoints, those outside the Base Plane (greater than U+0xFFFF) are not

428 Simplified (PRC) or Traditional (Taiwan)), or Japanese.

432 For Hong Kong, which uses Traditional Chinese and where Cantonese is the
433 dominant language, the Hong Kong Supplementary Character Set was added to
434 Unicode in 2005 and revised in 2009 (it is part of CJK Extension B and
435 contains more than 1900 characters). Earlier fonts will not be able to
436 support either Cantonese or use of these characters where local names are
437 written in Mandarin. The UMing HK, Noto Sans CJK HK and WenQuanYi Zen Hei
438 fonts all seem to cover Hong Kong usage
439 (<application>fontconfig</application> disagrees about Noto Sans CJK HK).

443 The Han glyphs are double-width, other glyphs in the same font may be

504 At one time there was a 1.6 release, and more recently some versions at

506 off the web and it is unclear if there was a problem.
507 <application>Fontconfig</application> does not know anything about the
508 later fonts (AR PL New Kai, AR PL New Sung Mono) and will default to
509 treating them as Sans.

552 <ulink

554 Zen Hei</ulink> provides a Sans-Serif font which covers all CJK scripts
555 including Korean. Although it includes old-style conf files, these are
556 not required: <application>fontconfig</application> will already treat
557 these fonts (the 'sharp' contains bitmaps, the monospace appears not
558 to be Mono in its ASCII part) as Sans, Serif, and Monospace. If all
559 you wish to do is to be able to render Han and Korean text without
560 worrying about the niceties of the shapes used, the main font from
561 this package is a good font to use.

595 to make it known to fontconfig, see <xref

626 In Korean, Batang or Myeongjo (the older name) are Serif, Dotum or

640 Fonts', then click on the font example to see more details including the
641 License, and click on the link to download it. For Nanum, you will need
642 to be able to read Korean to find the download link on the page you get
643 to. For Un there are direct links and you can find the un-fonts-core
