The current Debian Samba package uses the following shell snippet to
convert between 2.2-style character set settings and 3.0-style settings,
if the user has opted to let Debian manage the smb.conf file directly.
If the user has chosen to not allow automatic management of smb.conf, any
"character set" and "client code page" values in smb.conf will need to be
converted by hand to the new "unix charset" and "dos charset" values.

If the user previously had these settings in smb.conf, and they were
converted but accents are still broken, please let me know.  (Preferably,
a bug would be filed with the Debian BTS.)
