I modified the new VN (yet another newsreader) which was
recently distributed through mod.sources (v08i064~).
The original version was distributed through net.sources and
I posted the patch for it. I think that you can easy
modify the VN sources using a patch program.
I want to know how many sites use my patch and what kind of
kanji functions are requested to VN.
If you use it or you want to request new functions,
please send me a e-mail.

=====
The modified functions are following:
1) VN can run on BSD4.1.
2) VN can understand KANJI ESCape sequence.
Restriction:
For KANJI displayed function
1) A terminal has to understand that the 3 byte escape sequence
(" ESC $ F" F is any character) designate JIS6226.
2) A terminal has to understand that the 3 byte escape sequence
(" ESC ( F" F is any character) designate ASCII or JIS roma-ji.
TERMCAP:
When you use this kanji version, you have to modify your termcap.
You need to add AI (escape sequence to ascii) and KI (escape sequence
to JIS6226). (ex. AI=\E(H KI=\E$@ )
MAKEFILE:
A makefile I used is as followed:
----------------
CFLAGS= -O -DJOBCONTROL -DBSD41 -DKANJI -DWRONGESC
LIBS= -ltermcap -ljobs
OBJS= hash.o groupdir.o envir_set.o newsrc.o pagefile.o reader.o storage.o sig_set.o term_set.o tty_set.o userlist.o vn.o vnglob.o digest.o strings.o tmpnam.o reg.o strtok.o
vn: $(OBJS)
cc -o vn $(OBJS) $(LIBS)
----------------
I added definitions (BSD41 KANJI WORNGESC) in CFLAGS.
BSD41 is a define for BSD4.1.
KANJI is a define for KANJI ESCape sequences.
WRONGESC is a define for acceptance of the worng JIS ESCape sequence.
