Hello,

While trying to use a terminal program that can display
Chinese characters in zh_CN.GB2312 for testing my pending fixes
to the zh-autoconvert package, I installed rxvt-ml and tried
to use the old trusty crxvt-gb, but could not get it to display
any Chinese.  Looking deeper, it is even missing the -fm option
that can be used to choose a multibyte CJK font.

I then tried installing mrxvt-cjk, which works fortunately.
"mrxvt-cjk -h" shows the following:

    Mrxvt v0.5.4
    Options: fade,XIM,multichar_languages,scrollbars=xterm,Resources

But the current "crxvt-gb -h" instead shows:

    Rxvt v2.7.10 - released: 26 MARCH 2003
    Options: XPM,transparent,utmp,menubar,XIM,scrollbars=rxvt,graphics,XGetDefaults

Note the absence of "multichar_languages".

An examination of the rxvt source package reveals that upstream has
changed its ./configure options.  The old --enable-{kanji,gb,big5}
options were replaced with --enable-languages and the optional
- --with-encoding options some time in the 2.7.x release.

After applying the attached fix to debian/rules, I finally see that
beautiful "multichar_languages" string:

    Rxvt v2.7.10 - released: 26 MARCH 2003
    Options: XPM,transparent,utmp,menubar,XIM,multichar_languages,scrollbars=rxvt,graphics,XGetDefaults

And yes, it works!  "LANG=zh_CN.GB2312 crxvt-gb" now displays Chinese
characters correctly, and ditto for "LANG=zh_TW.BIG5 crxvt-big5"
and "LANG=ja_JP.EUC-JP krxvt".

Many thanks!

Anthony
