Produce a diagnostic highlighting some portion of a literal.
Emits the diagnostic DiagID, highlighting the range of characters from TokRangeBegin (inclusive) to TokRangeEnd (exclusive), which must be a substring of a spelling buffer for the token beginning at TokBegin.

EncodeUCNEscape - Read the Universal Character Name, check constraints and convert the UTF32 to UTF8 or UTF16.
This is a subroutine of StringLiteralParser. When we decide to implement UCN's for identifiers, we will likely rework our support for UCN's.
