    /* **************UTF-8 Validation methods and members*******************
    * The following text is taken from draft-yergeau-rfc2279bis-02 and explains
    * UTF-8 encoding:
    *
    *In UTF-8, characters are encoded using sequences of 1 to 6 octets.
    * If the range of character numbers is restricted to U+0000..U+10FFFF
    * (the UTF-16 accessible range), then only sequences of one to four
    * octets will occur.  The only octet of a "sequence" of one has the
    * higher-order bit set to 0, the remaining 7 bits being used to encode
    * the character number.  In a sequence of n octets, n>1, the initial
    * octet has the n higher-order bits set to 1, followed by a bit set to
    * 0.  The remaining bit(s) of that octet contain bits from the number
    * of the character to be encoded.  The following octet(s) all have the
    * higher-order bit set to 1 and the following bit set to 0, leaving 6
    * bits in each to contain bits from the character to be encoded.
    *
    * The table below summarizes the format of these different octet types.
    * The letter x indicates bits available for encoding bits of the
    * character number.
    *
    * <pre>
    * Char. number range  |        UTF-8 octet sequence
