That's interesting. I'm a bit spoiled by primarily using Vim to write code and prosé in American English. Vim's digraph feature (Ctrl-K by default) has handled unicode char input nicely enough for me, but I wonder if the compose key could be of use when writing text in Japanese for example.
I think it's no good for Japanese, but I know very little about Japanese input. Romanji is still Japanese, right?
