Description: 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.
