|

|
---|
| 110 | characters in the file's name.</para>
|
---|
| 111 | </note>
|
---|
| 112 |
|
---|
| 113 | <para>The <application>UnZip</application> package assumes that filenames
|
---|
| 114 | stored in the ZIP archives created on non-Unix systems are encoded in
|
---|
| 115 | CP850, and that they should be converted to ISO-8859-1 when writing files
|
---|
| 116 | onto the filesystem. Such assumptions are not always valid. In fact,
|
---|
| 117 | inside the ZIP archive, filenames are encoded in the DOS codepage that is
|
---|
| 118 | in use in the relevant country, and the filenames on disk should be in
|
---|
| 119 | the locale encoding. In MS Windows, the OemToChar() C function (from
|
---|
| 120 | <filename>User32.DLL</filename>) does the correct conversion (which is
|
---|
| 121 | indeed the conversion from CP850 to a superset of ISO-8859-1 if MS
|
---|
| 122 | Windows is set up to use the US English language), but there is no
|
---|
| 123 | equivalent in Linux.</para>
|
---|
| 124 |
|
---|
| 125 | <para>When using <command>unzip</command> to unpack a ZIP archive
|
---|
| 126 | containing non-ASCII filenames, the filenames are damaged because
|
---|
| 127 | <command>unzip</command> uses improper conversion when any of its
|
---|
| 128 | encoding assumptions are incorrect. For example, in the ru_RU.KOI8-R
|
---|
| 129 | locale, conversion of filenames from CP866 to KOI8-R is required, but
|
---|
| 130 | conversion from CP850 to ISO-8859-1 is done, which produces filenames
|
---|
| 131 | consisting of undecipherable characters instead of words (the closest
|
---|
| 132 | equivalent understandable example for English-only users is rot13). There
|
---|
| 133 | are several ways around this limitation:</para>
|
---|
| 134 |
|
---|
| 135 | <para>1) For unpacking ZIP archives with filenames containing non-ASCII
|
---|
[8fdf129] | 136 | characters, use <ulink url="http://www.winzip.com/">WinZip</ulink> while
|
---|
| 137 | running the <ulink url="http://www.winehq.com/">Wine</ulink> Windows
|
---|
[86eaa277] | 138 | emulator.</para>
|
---|
| 139 |
|
---|
| 140 | <para>2) After running <command>unzip</command>, fix the damage made to
|
---|
| 141 | the filenames using the <command>convmv</command> tool
|
---|
| 142 | (<ulink url="http://j3e.de/linux/convmv/"/>). The following is an example
|
---|
| 143 | for the ru_RU.KOI8-R locale:</para>
|
---|
| 144 |
|
