  Obviously, this isn't the right time for me to write these emails.
You're right.

  Other comment would be that if the platform needs to translate the
"char code" from the OS to Unicode, the translation table should be
canonicalized.  Different platforms could give you different Unicode
value for the "same" character...  Some issues we are going to have at
first, but things will stabilize after the first a few rounds...

  I confess.  I haven't.  Because I thought you guys were talking
about Scroll Events, and I just noticed that the conversation switched
to keyboard input.  (Bad excuse, I should've read.)

  Ok.

  Sorry!
