I'm almost positive Azeri has the same dotless i
issue and perhaps
some of the other Turkic languages of Central Asia. One solution is to
do accent/diacritic normalization too as part of the canonicalization.
This is getting into "nirvana fallacy" territory - we can't have
case-folding until every edge case works?
Instead, I would ask first: What does it take in English? Then work
out from there.
