I thought the whole point of moving from libc5 to libc6=glibc for CJK people was supporting these. From current "info Libc": As shown in some other part of this manual, a completely new family has been created of functions that can handle wide character texts in memory. The most commonly used character sets for such internal wide character representations are Unicode and ISO 10646 (also known as UCS for Universal Character Set). Unicode was originally planned as a 16-bit character set; whereas, ISO 10646 was designed to be a 31-bit large code space. The two standards are practically identical. They have the same character repertoire and code table, but Unicode specifies added semantics. At the moment, only characters in the first `0x10000' ... -- ~\^o^/~~~ ~\^.^/~~~ ~\^*^/~~~ ~\^_^/~~~ ~\^+^/~~~ ~\^:^/~~~ ~\^v^/~~~ +++++ Osamu Aoki @ Cupertino CA USA See "User's Guide": http://www.debian.org/doc/manuals/users-guide/ See "Debian reference": http://www.debian.org/doc/manuals/reference/ "Debian reference" Project at: http://qref.sf.net I welcome your constructive criticisms and corrections. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
