$XMODIFIERS, $LANG, and that of `locale-coding-system',

Hi again,

I reverted my change to the menu item, started Emacs, verified that I can't type ~, and performed:

Shell command: echo "$XMODIFIERS, $LANG"
@im=ibus, en_SE.UTF-8

This LANG value is what I get by default, don't know where it comes from but seems correct because I mostly use English but live in Sweden. I also tried to explicitly specify LANG=en_SV.UTF-8, doesn't work. As well as LANG=en_US.UTF-8 and LANG=sv_SE.UTF-8 which both work and as before LANG=C.UTF-8 which also works. I have not experienced any problems to type ~ in other applications. Seems to me that Emacs doesn't like when not using the main language for the chosen location... The value of XMODIFIER didn't change. Nor did the below variable:

Describe variable: locale-coding-system
locale-coding-system is a variable defined in ‘C source code’.

Its value is ‘utf-8-unix’

Coding system to use with system messages.
Also used for decoding keyboard input on X Window system, and for
encoding standard output and error streams.

  Probably introduced at or before Emacs version 21.1.
