Thanks.

For the record, my guess is that you will see Emacs getting a WM_CHAR
messages with character codes below 256, i.e. characters encoded in
the current ANSI codepage.  This is because in w32fns.c:w32_init_class
we call the ANSI variant of RegisterClass (since UNICODE is not
defined), which tells Windows that we want messages with text in the
ANSI character set.
