- # wcwidth
- Determine columns needed for a fixed-size wide-character string
- ----
- wcwidth is a simple JavaScript port of [wcwidth](http://man7.org/linux/man-pages/man3/wcswidth.3.html) implemented in C by Markus Kuhn.
- JavaScript port [originally](https://github.com/mycoboco/wcwidth.js) written by Woong Jun <woong.jun@gmail.com> (http://code.woong.org/)
- ## Example
- ```js
- '한'.length // => 1
- wcwidth('한'); // => 2
- '한글'.length // => 2
- wcwidth('한글'); // => 4
- ```
- `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 the given wide character and string.
- Markus's implementation assumes the wide character given to those
- functions to be encoded in ISO 10646, which is almost true for
- JavaScript's characters.
