I briefly tried it (will do more testing once NEWS or the manual
describes the feature in detail), and saw one problem: the Unicode
character → (u+2192) is a problem on TTYs that can't encode it or on
GUI frames that use font without a glyph for it.  So I think we need a
fallback for those cases (e.g., using char-displayable-p to detect them).

Thanks.
