Subject: Re: git on MacOSX and files with decomposed utf-8 file names

Linus Torvalds:


I'd prefer not to.


It is relevant because the Mac OS file system stores file names as a
sequence of Unicode code points, in a (apparently slightly modified)
normalized form, whereas Git prefers to see file systems that store
file names as a sequence of octets, which may, or may not, actually map
to something that the user would call characters.

I happen to prefer the text-as-string-of-characters (or code points,
since you use the other meaning of characters in your posts), since I
come from the text world, having worked a lot on Unicode text
processing.

You apparently prefer the text-as-sequence-of-octets, which I tend to
dislike because I would have thought computer engineers would have
evolved beyond this when we left the 1900s.

But the real issue is that Git cannot use it's filenames as string of
octets on Mac OS X, since the file system doesn't handle it. So Git
needs to do something sensible. That's part of porting. Preferrably
that would involve supporting real Unicode file names, which would also
work on Windows (through it's UTF-16 file APIs), and in part on other
systems (through conversion to the systems' locale encoding).
