I've looked into this a bit. git ls-files will return all filenames c-style quoted. Hence the filename åäö will be returned as 303245303244303266. This is of course also wrong as it should be \303\245\303\244\303\266. However, if we tell git ls-files to use \0 instead of \n for line termination. We get åäö returned. So how can the choose of line termination effect the encoding? Look in quote.c. The following patch will solve this particular problem (but break other usecases!) diff --git a/quote.c b/quote.c index 911229f..2870ca5 100644 --- a/quote.c +++ b/quote.c @@ -284,7 +284,7 @@ void quote_two_c_style(struct strbuf *sb, const char *prefix, const char *path, void write_name_quoted(const char *name, FILE *fp, int terminator) { if (terminator) { - quote_c_style(name, NULL, fp, 0); + fputs(name, fp); } else { fputs(name, fp); } Why don't we always print names quoted?
