Are you still thinking about the single on/off switch?

I agree that saying "Japanese identifiers are OK from now on" still
shouldn't turn on Cyrillic identifiers.  I think the current
alternative boils down to some variant of

    python -idchars allowedchars.txt

where allowedchars.txt would look something like


0780..07B1    ; Thaana

or

10000..100FA  ; Linear_B plus some blanks I was too lazy to exclude

(These lines are based on the unicode Scripts.txt, and use character
ranges instead of script names so that you can exclude certain symbols
if you want to.)
