Hej Jeffrey, I am not an iconv expert - and don't intend to become one. The UTF-8-MAC conversion does probably only exist in the code for iconv shipped on Mac OS - so it could happen that this code is not open source. There may be ways to "extract it" : Either that information is part of the unicode specification, and there may be tables that can be converted into c-code that fits into the iconv code base. I don't know. Or you can use the iconv on MacOs itself to generate such a table. That is all somewhat behind my horizon. For Git (under MacOS) we need UTF-8-MAC to compensate for HPS, (or HPF+) so that all filenames with non-ASCII codepoints are stored in the repo in precomposed unicode. This is what Linux and Windoes and Unix is using, this commit may give more information about the what and why: commit 76759c7dff53e8c84e975b88cb8245587c14c7ba Author: Torsten Bögershausen <tboegi@xxxxxx> Date: Sun Jul 8 15:50:25 2012 +0200 git on Mac OS and precomposed unicode By the way, does ./t3910-mac-os-precompose.sh work on your system ? So far I am not aware about any problems with iconv from MacOs being reported here on the list. Which problems/bugs did you found in the iconv shipped with MacOs, especially together with Git ?
