    Check if String.prototype.toLocaleLowerCase supports conditional mappings defined in SpecialCasings,
    test Final_Sigma context with Mongolian Vowel Separator

    The result must be derived according to the locale-insensitive case mappings in the Unicode Character
    Database (this explicitly includes not only the UnicodeData.txt file, but also all locale-insensitive
    mappings in the SpecialCasings.txt file that accompanies it).
