A multitude of character string/text/natural language processing tools: pattern
searching (e.g., with 'Java'-like regular expressions or the 'Unicode'
collation algorithm), random string generation, case mapping, string
transliteration, concatenation, sorting, padding, wrapping, Unicode
normalisation, date-time formatting and parsing, and many more. They are fast,
consistent, convenient, and - owing to the use of the 'ICU' (International
Components for Unicode) library - portable across all locales and platforms.
