Unfortunately, Aspell does not support Unicode, so far as I can tell. I grabbed aspell-0.50.3, and it still has utf-8 support on the todo list. Aspell seems to supersede pspell which supersedes ispell; I don't know of any spell checker (except for my own, which doesn't generate suggestion lists) that handles utf-8.
My Yiddish ispell dictionary is usable, but it never suggests removing a letter or adding a letter (that's a two-byte change!), and it can't be set to ignore Yiddish open and close quotes, because their first byte in UTF-8 looks just like the first byte of many other letters. By the way, I don't see my Yiddish dictionary on the download page for AbiWord internationalizations; it should be placed there, even though ispell's ability to manipulate it is substandard. At least it generally shows what words are misspelled. Raphael
