This is what it should be: http://www.fredericcote.ca/ ? Interesting. I love it. But it's rather un-American, of course.
I'm working in The Netherlands. Even here we have problems with it. A website where people could enter their name for a magazine subscription gave us the name in Unicode, but our system 'forgot' to translate it to Windows-1252. And I got a file from the subscription administration system of another publisher where all such characters (when I opened the file in Wordpad) were just a question mark and no more. I asked if it was OK in their system, but didn't get an answer yet.
Long ago, when disk space was at a premium (1975) we had a subscription system that only registered 4 initials (like CKLT Surname, no space for dots of course). That gave complaints of people insisting in seeing all 5 initials (C.K.L.T.M. Surname).
