> Currently SqlCollation defines concepts like Coercibility, Charset, Locale, etc. However, we cannot specify on a certain collation that e.g. a string field should use case insensitive comparison. The goal of this ticket is to evolve SqlCollation to support that, and adapt the corresponding classes to use that (optional) "non-standard" comparison.
