UnicodeCollation class abstract final Query Builder

Unicode Collation that will compare two strings by using the Unicode collation algorithm.

If the local is not specified, the collation is Unicode-aware but not localized; for example, accented Roman letters sort right after the base letter (This is implemented by using the "en_US" locale.).
