From: Ben Wing [mailto:ben＠666.com]
NOTE: One possible default internal representation that was
compatible
with UTF16 but allowed all possible chars in UCS4 would be to take an
unused range of 2048 chars (not from the private area because
Microsoft
actually uses up most or all of it with EUDC chars).
Aren't the extra code points you want access to user defined characters
anyway?
I could try some prodding to see if the folks here at MS would be willing to
release the process they use to map DBCS EUDC into Unicode private area
space based on the codeset if you want.

In order to save my hands, I am cutting back on my mail. I also write
as succinctly as possible -- please don't be offended. If you send me
mail, you _will_ get a response, but please be patient, especially for
XEmacs-related mail. If you need an immediate response and it is not
apparent in your message, please say so. Thanks for your understanding.
