UCA (Unicode Collation Algorithm) support.
Written by Alexander Barkov <bar@mysql.com>
Currently supports only subset of the full UCA.
Currently supports only subset of the full UCA:
- Only Primary level key comparison
- Basic Latin letters contraction is implemented
- Variable weighting is done for Non-ignorable option
Features that are not implemented yet:
- No Normalization From D is done
+ No decomposition is done
+ No Thai/Lao orderding is done
- No contraction is done
- No combining marks processing is done
