commit 60cc4a18e6a2c865e250609a3021fa4ff2b57650
Author: Andreas Schwab <schwab@linux-m68k.org>
Date: Mon Feb 6 13:30:45 2012 +0100
Complete GB18030 charmap
Andreas updated the localedata/charmaps/GB18030 with additional mappings. The
provenance of those is unclear. They do not agree with the mapping table here:
http://source.icu-project.org/repos/icu/data/trunk/charset/data/xml/gb-18030-2000.xml
The difference is related to this choice in the glibc charmap
% <UE78D> /xa6/xd9 <Private Use>
% <UE78E> /xa6/xda <Private Use>
% <UE78F> /xa6/xdb <Private Use>
% <UE790> /xa6/xdc <Private Use>
% <UE791> /xa6/xdd <Private Use>
% <UE792> /xa6/xde <Private Use>
% <UE793> /xa6/xdf <Private Use>
% <UE794> /xa6/xec <Private Use>
% <UE795> /xa6/xed <Private Use>
% <UE796> /xa6/xf3 <Private Use>
versus:
<UFE10> /xa6/xd9 PRESENTATION FORM FOR VERTICAL COMMA
<UFE11> /xa6/xdb PRESENTATION FORM FOR VERTICAL IDEOGRAPHIC COMMA
<UFE12> /xa6/xda PRESENTATION FORM FOR VERTICAL IDEOGRAPHIC FULL
STOP
<UFE13> /xa6/xdc PRESENTATION FORM FOR VERTICAL COLON
<UFE14> /xa6/xdd PRESENTATION FORM FOR VERTICAL SEMICOLON
<UFE15> /xa6/xde PRESENTATION FORM FOR VERTICAL EXCLAMATION MARK
<UFE16> /xa6/xdf PRESENTATION FORM FOR VERTICAL QUESTION MARK
<UFE17> /xa6/xec PRESENTATION FORM FOR VERTICAL LEFT WHITE
LENTICULAR BRACKET
<UFE18> /xa6/xed PRESENTATION FORM FOR VERTICAL RIGHT WHITE
LENTICULAR BRAKCET
<UFE19> /xa6/xf3 PRESENTATION FORM FOR VERTICAL HORIZONTAL ELLIPSIS
It is not clear to me which one is correct. Emacs chooses the <UE78D>
mappings, too.
Maybe the mapping changed over time, or there are conflicting practices. Even
if it's a Private Use codepoint on the Unicode site, there should be a definite
mapping.
