- // non-ASCII space is any Unicode code point having a general
- // category of "Zs", naturally with the exception of SPACE
- // (U+0020). (The inclusion of only ASCII space prevents
- // confusion with various non-ASCII space code points, many of
- // which are difficult to reproduce across different input
- // methods.)
- //
- // b. Remove any instances of the ASCII space character at the
- // beginning or end of a nickname (e.g., "stpeter " is mapped to
- // "stpeter").
- //
- // c. Map interior sequences of more than one ASCII space character
- // to a single ASCII space character (e.g., "St Peter" is
- // mapped to "St Peter").
