Only if one blindly relies on the answer.
I'd recommend against relying on fuzzy comparisons to do updates.
Any locale dependant comparison is by definition not a single mapping
across all systems. Any case ignoring comparison is locale dependant - the
standards decree this.
So?
So the only non fuzzy comparison you can rely on is a case dependant one.
Fuzzy is what is being asked for.
put every UTF character in its own bin
for U in UTF_characters :
for Loc in Locales :
for V in UTF_characters :
if U and V match in Loc :
merge bin of U with bin of V
For fuzzy matching purposes, characters in the same bin match.
