It looks like Romanian also has s with comma. Perhaps we should have
all these characters:
$ curl -s http://unicode.org/Public/7.0.0/ucd/UnicodeData.txt | egrep
';LATIN (SMALL|CAPITAL) LETTER [A-Z] WITH ' | wc -l
702
That's quite a lot more than the 187 we currently have. Of those, I
think only the following ligature characters don't fit the above
pattern: =C3=86, =C3=A6, =C4=B2, =C4=B3, =C5=92, =C5=93, =C3=9F. Incidenta=
lly, I don't believe that the
way we "unaccent" ligatures is correct anyway. Maybe they should be
expanded to AE, ae, IJ, ij, OE, oe, ss, respectively, not A, a, I, i,
O, o, S as we have it, but I guess it depends what the purpose of
unaccent is...
