It would show the user that she is dealing with ligatures though.

It's not Unicode's fault - it's the world's fault for not just speaking American English d-; But hey, Word seems to work. I have no idea what Word does for the fi ligature and friends though. I'd guess that if it's entered as a precomposed glyph it will handle it as a single glyph. If it's entered as 'f' plus 'i' it will never convert it to a ligature.
