[Q] How to retrieve / set current TCC/LE language

Hello. Me again.

1. To retrieve current TCC' language I can examine [tcc.ini]LanguageDLL
Is there any simple conversion (API or command) to get "standardized" name? "en", "de", "ru" etc.

2. Is it possible to force to reload LanguageDLL from command line?
Simply changing tcc.ini is not enough, tcc doesn't reloads it (as documented)
option //LanguageDLL=Russian.dll changes [tcc.ini]LanguageDLL to correct value, but to use it I have to invoke Option command without params and press OK

Best Regards
