| # 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. |
