Subject: javascript: Simplify Unicode character escape handling
X-Git-Tag: v0.19.4~62
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c412fc08868f583b8ae0a09bdb2699164849aa4c;p=thirdparty%2Fgettext.git

javascript: Simplify Unicode character escape handling

ECMA-262 only supports "\uXXXX" style Unicode character escape and
we don't need extra space for character names.
* x-javascript.c: Don't include "uniname.h".
(phase2_pushback): Decrease to 5.  Don't refer to UNINAME_MAX.
