I was under the impression though that the meaning of a word, unlike fiancée/fiancee, could change. My spellchecker BTW flags the latter as misspelled.
As to the technical side, I don't think I know any more than you do. I just know that the people I was dealing with couldn't seem to get their characters on the screen in the browser without UTF-16.
