annotate lisp/mule/mule-composite-stub.el @ 5565:48a3d3281b48
Pass eighth bit on TTY consoles to coding system if needed.
src/ChangeLog addition:
2011-09-06 Aidan Kehoe <kehoea@parhasard.net>
* redisplay-tty.c (init_tty_for_redisplay):
Only set the console meta key flag to treat the eight bit as meta
if the native coding system doesn't need that.
* general-slots.h:
* mule-coding.c:
* mule-coding.c (syms_of_mule_coding):
Move Qiso2022, Qseven to general-slots.h, they're now used in
redisplay-tty.c.
lisp/ChangeLog addition:
2011-09-06 Aidan Kehoe <kehoea@parhasard.net>
* mule/mule-cmds.el (set-language-environment-coding-systems):
Set the input mode for TTY consoles to use the eighth bit for
character information if the native coding system for the language
environment needs that.
