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. following the original implementation, this library defines the column width of an iso 10646 character as follows: - the null character (u+0000) has a column width of opts.null (whose default value is 0); - other [c0/c1 control characters] and del will lead to a column width of opts.control (whose default value is 0); - non-spacing and enclosing combining characters ([general category
