Unicode normalization

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Has somebody integrated Unicode normalization into Postgres? if not, I would have to implement my own function by using this CPAN module: http://search.cpan.org/~sadahiro/Unicode-Normalize-1.03/ .

I need a function which removes all diacritics (1) and transforms some characters to a more compatible form (2) to get a better index on strings.

Best,

Andi
