Whenever the Windows API has to convert between Unicode strings and char* strings, it uses the current "ANSI code page". As far as I know, the UTF-8 codepage (65001) cannot be used as the "current ANSI code page". Users will always have some code page set that is not UTF-8. For example, if the user specifies a file name on the command line, than it will not enter git in UTF-8, but in the current "ANSI" or "OEM code page" encoding. If git prints a file name under the assumption that it is UTF-8 encoded, then it will be displayed incorrectly because the system uses a different encoding. > Since there is no real file system abstraction beyond using stdio > (AFAIK), I need to hack it by replacing fopen (and open).

I think you are grossly underestimating the venture that you want to undertake here. Please come up with a plan how you are going to deal with the various issues. File names enter and leave the system through different channels: - the command line and terminal window - object database (tree objects) - opendir/readdir; opening files or directories for reading or writing And there is probably some more... How do you treat encodings in these channels? What if the file names are not valid UTF-8? Etc. The biggest obstacle will be that git does not have a notion of "file name encoding" - it simply treats a file name as a stream of bytes. There is no place to write an encoding. If the byte streams are regarded as having an encoding, then you can have ambiguities, mixed encodings, or invalid characters. You would have to deal with this in some way. > This will lose all chances of Windows 9x compatibility, but I don't know > if there are any attempts of supporting it anyway? Windows 9x is already out of the loop. We use GetFileInformationByHandle() that is only available since Windows 2000. -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
