Re: [PATCH] git svn: add an option to recode pathnames

[Robert Pollak <robert.pollak@gmail.com>]

Introduce a new option 'svn.pathnameencoding' that instructs git svn to
recode pathnames to a given encoding.  It can be used by windows users
and by those who work in non-utf8 locales to avoid corrupted file names
with non-ascii characters.

Hello Eric,

since the patch is useful to me, I have made the requested option name
change and added some manpage documentation. Please consider applying the
patch or give me additional feedback.

This is the first patch I submit on this list, so I hope it's ok.

Best regards,
Robert
