Description of problem:
It does not seem to be a way to specify a desired coding in profiles.
As a command line option to do that is not apparent as well then I do
not see how to create icons and/or menu entries to open terminals
with various codings. This effect is trivially achievable with earlier
version of Gnome by picking up in profiles a proper font set which,
regretably, is no longer possible. Mousing all the time quickly becomes
old especially that "Reset Terminal" resets also coding to a default.
This is already filed on gnome.org I believe, or at least I looked at it a bit.
The reason it's not there is that the default encoding is currently from $LANG
If it's in the profile it probably has to have a "use $LANG" option which
would be the default.
It's possible some sort of "env variables to set" feature for profiles
would be more generally useful and also fix this.
