That's true.

‌There are about 163 senders just in Etoys image and some of them are quite 
valid (i.e. they do apply for lang=0,value<128 case. 
HandMorph>>generateKeyboardEvent is not one of them, so ‌I ‌go ahead fix these

Yes. the issue is common but the fix is non-trivial. Latin1 languages can have 
either UTF32InputInterpreter or UTF8InputInterpreter depending on the codeset 
being used. LocalePlugin has to be extended to return codeset (nil, UTF-8, 
...) and modifier on Unix.

For solving the current issue, I will patch the immediate asciiValue misuse 
and create a changeset for UTF8Environment that should cover most of the 
multilingual issues for non-Latin languages. For en, ‌I will add a m17n 
preference that will switch between classic codesets and UTF-8 codeset.
