description: Template values of UTF-16 escape sequences
info: |
    The TV of TemplateCharacter :: \ EscapeSequence is the SV of
    EscapeSequence.
    The SV of UnicodeEscapeSequence :: u{ HexDigits } is the UTF16Encoding
    (10.1.1) of the MV of HexDigits.
    The TRV of UnicodeEscapeSequence :: u Hex4Digits is the sequence consisting
    of code unit value 0x0075 followed by TRV of Hex4Digits.
    The TRV of UnicodeEscapeSequence :: u{ HexDigits } is the sequence
    consisting of code unit value 0x0075 followed by code unit value 0x007B
    followed by TRV of HexDigits followed by code unit value 0x007D.
