>Description:
Hello. I use "mount_msdosfs -D cp1251 -L ru_RU.KOI8-R /dev/ad1s5 /mnt" for mounting vfat filesystem with codepage CP1251 (in system with ru_RU.KOI8-R locale). All filenames in /mnt are gambled. English filenames too! For example dot symbol become asterisk.

I have the same trouble with generic kernel or when i use "-W koi2dos" instead  "-D cp1251". I  notice english filenames gambling only when i use  -L or -W or -D in mount_msdosfs or -C in mount_cd9660.
It seems to me, that this is observed only with amd64 kernel.

Everything is OK with FreeBSD 5.2.1 i386 on the same hardware with identical settings (tty: cons25r, login class: russian, LANG=ru_RU.KOI8-R, MM_CHARSET=KOI8-R) and identical commands.

Excuse me, my english is poor.
>How-To-Repeat:
In FreeBSD5.3-RELEASE amd64 mount vfat partition with codepage cp1251 using command like:
mount_msdosfs -D cp1251 -L ru_RU.KOI8-R /dev/ad1s5 /mnt
