'\label{}' under automate prompt mechanism on echo area will not accept
Chinese character as valid character. And I'm doubt that this may not
only don't accept Chinese character but also for all non-latin
character.
Here is an example: with C-c C-e to input `environment' such as fig
which will automate prompt \label{fig:?} upon echo area. In such a
situation, I input Chinese `character' with my system input method in
echo area, and which is `success', but while I finished this and input
"Enter" to let the process finished, and the `character' been accept as
label keywords such as \label{fig: 图}， this prompt mechanism will
prompt me "character invalid". And seems like only Latin character is
acceptable. Is this progress expression cleared?
Not only C-c C-e but also C-c C-s which auto insert section with label,
and label in such also the same situation.
I did think this was a thing with Auctex, but while I use cdlatex, C-c {
for auto insert some thing with label prompt upon echo area, the same
"invalid `character'" will emerge.
For now, I'm not sure which level is this related, Emacs TeX system
level or Plug Level such as auctex or cdlatex.
And Is there someone did encounter this, could I change this situation
with .emacs/init.el config file?
For additional explanation, I'm sure Chinese character in \label{fig: 图}
is valid references method under xelatex and lualatex, just need "ctex"
package with in \usepackage.
