Description Hin-Tak Leung 2015-09-19 17:10:07 UTC
wine's kernel32 IsValidCodePage() supports code page 10000 to 10008 : 

wine/libs/wine/c_10000.c
wine/libs/wine/c_10001.c
wine/libs/wine/c_10002.c
wine/libs/wine/c_10003.c
wine/libs/wine/c_10004.c
wine/libs/wine/c_10005.c
wine/libs/wine/c_10006.c
wine/libs/wine/c_10007.c
wine/libs/wine/c_10008.c

This filters into MS.net's System.Text.Encoding.GetEncoding() running under wine also.

Mono's System.Text.Encoding.GetEncoding in I18N.dll does not support these Mac code pages.

Microsoft's Font Validator
(https://www.microsoft.com/typography/FontValidator.mspx)
when analysis fonts of Macintosh origin, can try to access code page 10001 to 10008 .

The first step would be to get the UCM files from ICU for those codepages.
