| 7 | wcwidth is a simple JavaScript port of [wcwidth](http://man7.org/linux/man-pages/man3/wcswidth.3.html) implemented in C by Markus Kuhn.

| 9 | JavaScript port [originally](https://github.com/mycoboco/wcwidth.js) written by Woong Jun <woong.jun@gmail.com> (http://code.woong.org/)

| 11 | ## Example
|
|---|
| 12 |
|
|---|
| 13 | ```js
|
|---|
| 14 | '한'.length // => 1
|
|---|
| 15 | wcwidth('한'); // => 2
|
|---|
| 16 |
|
|---|
| 17 | '한글'.length // => 2
|
|---|
| 18 | wcwidth('한글'); // => 4
|
|---|
| 19 | ```

| 21 | `wcwidth()` and its string version, `wcswidth()` are defined by IEEE Std
|
|---|
| 22 | 1002.1-2001, a.k.a. POSIX.1-2001, and return the number of columns used
|
|---|
| 23 | to represent the given wide character and string.
|
|---|
| 24 |
|
|---|
| 25 | Markus's implementation assumes the wide character given to those
|
|---|
| 26 | functions to be encoded in ISO 10646, which is almost true for
|
|---|
| 27 | JavaScript's characters.
