Harold,

It was posted in discussion board.

He said that 
"This fix following two problem.
1. X freeze when we have 2 byte string after 1 byte string using
  ASTEX-X's XIM.
2. We can't use XIM on Cygwin/XFree86 4.1.0 etc."

Second problem is fixed
http://cvsweb.xfree86.org/cvsweb/xc/lib/X11/lcSjis.c.diff?r1=3.9&r2=3.10
and
http://cvsweb.xfree86.org/cvsweb/xc/lib/X11/lcEuc.c.diff?r1=3.11&r2=3.12
that Allow UTF8 conversion to work for Japanese locales (#A.1527, Etsushi Kato).

So I delete code that related 2nd problem.

I write about 1st problem.
CTEXT has GL and GR two graphic character sets.
But CTEXT to multi-byte string/wide string converter in lcSjis.c
and lcEuc.c have only signle set. So text use GR convertion fail.
Those fix patch was wrote by TAKABE.

I added following code.
if (charset == ct_state.GR_charset) {
    clen = charset->length;
    do {
	(*(Uchar *)(ctptr-clen)) = BIT8ON(*(Uchar *)(ctptr-clen));
    } while (--clen); 
}
Because multi-byte text to CTEXT converter in lcSjis.c doesn't
set 8-bit on even if it is in GR.

I don't know his mail address.
