# In MySQL 5.5+ error messages are always constructed server-side as UTF-8
    # then returned in the encoding set by the `character_set_results` system
    # variable.
    #
    # See http://dev.mysql.com/doc/refman/5.5/en/charset-errors.html for
    # more context.
    #
    # Before MySQL 5.5 error message template strings are in whatever encoding
    # is associated with the error message language.
    # See http://dev.mysql.com/doc/refman/5.1/en/error-message-language.html
    # for more information.
    #
    # The issue is that the user-data inserted in the message could potentially
    # be in any encoding MySQL supports and is insert into the latin1, euckr or
    # koi8r string raw. Meaning there's a high probability the string will be
    # corrupt encoding-wise.
    #
    # See http://dev.mysql.com/doc/refman/5.1/en/charset-errors.html for
    # more information.
    #
    # So in an attempt to make sure the error message string is always in a valid
    # encoding, we'll assume UTF-8 and clean the string of anything that's not a
    # valid UTF-8 character.
    #
    # Returns a valid UTF-8 string.
