+# 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.
