Aside from font issues, Unicode normalization uses huge tables which might
not be practical for some devices which do support email. Therefore
transcoding a space- and memory-efficient charset into Unicode may
well render the transformed message unusable or unreplyable if
transferred (forwarded, etc.) to some devices [it is not unusual for
mail to be forwarded to PDAs, mobile phones, pagers, etc.].
Some chap at a Unicode conference talked about a trie-based
implementation that squeezed the tables into 35k. I believe he was from
Psion.
35k isn't huge, not even on a handheld.
