Alas, it seems that it is not possible. Argh. Now for unrelated approach number 2.
Method #2 has failed as well... Urk. This is annoying. I don't want to have to translate every character into a number and post those with an ampersand and a semicolon (if you've ever coded HTML, you know what I mean), that's a pain and a half. Galeon (Mozilla internally) won't accept pasted Japanese text (although IE will, but I don't want to have to find a Windows box to post on, I want to do it here where I read and email and all that crap -- in Japanese already fer crissakes).
I suppose I'll have to do some investigating.
