svn: E000022: Error converting entry in rver-v2/tags/2.0.0/bin/servers/default/transl

While trying to do a svn update here on my graal_reborn directory on Linux I get the following error:
svn: E000022: Error converting entry in directory ‘/home/paul/graal_reborn/gserver-v2/tags/2.0.0/bin/servers/default/translations’ to UTF-8

[paul@localhost graal_reborn]$ ls gserver-v2/tags/2.0.0/bin/servers/default/translations/
deutsch.po* espa?ol.po* italiano.po* norsk.po* svenska.po*
english.po* fran?ais.po* nederlands.po* portugu?s.po*

Actually, the directory come from my USB key. But I guess this is not the point.

It would probably not cause problems if accentuated letters had not been choses in filenames.
Not sure if it still can be fixed. Perhaps I could choose an appropriate locale… Windows one?

http://svnbook.red-bean.com/en/1.7/svn.advanced.l10n.html is giving more details on this ‘error’.

Those files should be named with a-z (all-lowercase) only IMO. I dunno why Joey chose to name them like that.

Well, frankly, I guess the fact that I used svn on a Windows box, then put the graal_reborn directory on my USB key, and then took the directory to my Linux box, and then tried to svn update on the Linux box, have to do with my problem.

I am not too familiar with these gettext stuff. I am reading ‘info gettext’ now.
From it, I conclude that these files, should be named LL.po where LL is the two letters code for that language in ISO 639:

Yes, copying between filesystems can be an issue. If so, the smartest way to go is Linux -> Windows and not the other way around. Linux is case-sensitive while Windows is not. This can cause a lot of issues.

On another note, did you read my message in the other thread?
