The problem is not particularly that UTF-8 can't travel down a
channel intended for ISO-8859-1. It's left and right, single and
double quotes - Windows-1252 codes 0x91 to 0x94. The Yahoo post to e-
mail converter assumes that the posting must be in Windows-1252 (
http://www.microsoft.com/globaldev/reference/sbcs/1252.htm ) and
converts these four bytes to the nearest ISO-8859-1 equivalent. This
results in the sequence being illegal UTF-8, hence the question marks
that sometimes appear.

It wasn't a clash with C1 control codes, which is what I had assumed.
(They are in the 'ISO-8859-1' _encoding_, but not in ISO 8859-1!)

Anyway, the upshot is - if you want to post UTF-8, use e-mail, not
the Yahoo web page. The sad thing then is that the thread links are
frequently broken when replies are e-mailed.
