Hey!
I've add UNICODE support to the Joliet patch.
It contains few charsets now, but to add other charsets is very easy.
Currently, iso8859-1 and euc-jp is included.
Mixture of Joliet/RockRidge Extension is also available, however untested.
How to use:
1. Pick up the patch from the URL.
http://triaez.kaisei.org/~mzaki/joliet/joliet.unicode.patch.gz
It contains huge table which provides conversion
from unicode character to euc-jp, so that the gzip'ed size is 36k.
So I give up to attach the patch to this mail.
2. Apply the patch to the source tree.
#cd /usr/src
#zcat /tmp/joliet.unicode.patch.gz|patch -p1
3. Make and install new mount_cd9660(8)
#cd /usr/src/sbin/mount_cd9660
#make; make install
4. Reconfig and reinstall your kernel and reboot.
5. Tell your kernel the charset you prefer.
#sysctl -w vfs.charset=iso8859-1
Currently, only 'none', 'iso8859-1' and 'euc-jp' is available.
none : The filenames are assumed to have 8bit character ONLY.
This is not recommended.
iso8859-1 : 8bit characters.
All 16bit characters (include russian, greek, chinese, etc.)
are replaced with numerical ('0'-'9').
euc-jp : Japanese characters.
This corresponds to the userland locale 'ja_JP.EUC'.
All characters unable to express are
replaced with numerical ('0'-'9').
How to use other charsets:
1. Look at the /sys/isofs.
charset and encoding directories are added.
For Europians, to make new charset/*.c is sufficient.
For Asians (Chinese, Korean, Japanese and so on),
to make new encoding/*.c is also required.
charset/*.c should contains Code Conversion Table.
Currently, only 'UNICODE -> local charset' conversion is needed.
(in future, reverse conversion may needed for msdosfs and ntfs.)
encoding/*.c should contains multibyte encoding routines.
These are subset of rune(3) at /usr/src/lib/libc/locale/
At least, MSKanji is required for ja_JP.SJIS, BIG5 for zh_TW.BIG5,
also UTF-8 for all UNICODE locale.
2. Add new file entries to /sys/conf/files
3. Reconfig and reinstall your kernel and reboot.
More documents are now scheduled in some days at the URL
