>Organization:
Atlantis ISP
>Environment:
FreeBSD homelynx.homenet 5.3-RELEASE-p2 FreeBSD 5.3-RELEASE-p2 #0: Wed Dec 22 01:35:24 EET 2004 root@homelynx.homenet:/usr/obj/usr/src/sys/lynx i386
>Description:
5.3-RELEASE can't handle some characters of the KOI8-U charset
in filenames on FAT-32 file system, namely (from RFC2319):
<decimal> <hex-code> <UCS> <description>
166 A6 U0456 CYRILLIC SMALL LETTER BYELORUSSIAN-
UKRAINIAN I
173 AD U0491 CYRILLIC SMALL LETTER GHE WITH UPTURN
182 B6 U0406 CYRILLIC CAPITAL LETTER
BYELORUSSIAN-UKRAINIAN I
189 BD U0490 CYRILLIC CAPITAL LETTER GHE WITH UPTURN
One can create files with those characters in filename under MS Windows
or FreeBSD 4.11-RELEASE (filesystem mounted there with additional parameters in fstab: -L=uk_UA.KOI8-U,-W=koi8u2dos), and both systems
can access resulting files, Windows doesn't detect violations of disk
structure. But when I mount this slice under 5.3-RELEASE (I'm using additional parameters -L=uk_UA.KOI8-U,-D=CP866 as -W deprecated in RELENG_5 and mount_msdosfs internally replaces it whit -D=CP866 anyways), ls -l and other utilities say "ls: X: Invalid argument" where
X is a file name with a "forbidden" letter.
>How-To-Repeat:
Under 4.11-RELEASE: mount FAT-32 partition with uk_UA.KOI8-U locale
(-L=uk_UA.KOI8-U,-W=koi8u2dos) and create file with the name, say, Ukrainian I (character code differs from English I). Then reboot to 5.3-RELEASE, mount the same partition with uk_UA.KOI8-U locale (now use
-L=uk_UA.KOI8-U,-D=CP866) and try to ls -l or fstat this file.
