wcwidth.js is a javascript porting of C's wcwidth()

wcwidth.js is a simple javascript porting of wcwidth() implemented in C by Markus Kuhn.

wcwidth() and its string version, wcswidth() are defined by IEEE Std 1002.1-2001, a.k.a. POSIX.1-2001, and return the number of columns used to represent a wide character and string on fixed-width output devices like terminals. Markus's implementation assumes wide characters to be encoded in ISO 10646, which is almost true for JavaScript; almost because JavaScript uses UCS-2 and has problems with surrogate pairs. wcwidth.js converts surrogate pairs to Unicode code points to handle them correctly.

Node.js is an event-based server-side JavaScript engine.
