AFAICS reseat routines uses bidi_init_it to make sure that BIDI stuff
is synced with the rest of redisplay, isn't it?

Did you see some evidence that the call to CHAR_TO_BYTE is redundant
in the general case?

I just tried the patch from the previous e-mail in the very basic editing
session against a few files (including Greek and R2L Arabic scripts), and
eassert was never triggered.
