In article <CABuGu1qHrfOggr=zpc3xM12d7obzEGfvGgET4U_iSE0aU1OChg@mail.gmail.com> you write:

No, never.  There is no way to re-code a UTF-8 local part.  Don't even
ask.

If it sounds like I've had this argument before, I have and I really
don't want to have it again.

R's,
John

PS: even if we were to invent some crock like turning UTF-8 into hex,
it would not work because there are a vast number of ways to encode
strings in UTF-8 that look identical, and there is no plausible way to
normalize them all.  It's not like ASCII case folding.
