Pattern Matching Operations

Text pattern matching and searching operations with support for different UTF encodings between pattern definitions and input text.

• Use Regex_<T> for pattern definition with ObjectString<T> encoding
• Use MatchHead<U> for finding longest prefix matching the pattern
• Use Match<U> for finding earliest substring matching the pattern
• Use TestHead<U> for boolean prefix matching without detailed results
• Use Test<U> for boolean substring matching without detailed results
• Use Search<U> for appending all non-overlapping successful matches to RegexMatch_<U>::List
• Use Split<U> for appending delimiter-separated unmatched fragments to RegexMatch_<U>::List
• Use Cut<U> for appending both successful and failed fragments in order
