I wrote a couple of Unicode text editors that would have been a
nightmare if they had not been operating on UTF-32.

Actually in a few cases I have seen it is not the compressed size but
the conversion performance [memory/CPU] that hurts. It is much better to
get the correct encoding for the correct use case.
