## FAQ
|
||
|
|
|
||
|
|
### 1. What is this library for?
|
||
|
|
|
||
|
|
This library converts a Unicode encoded domain name to a IDNA ASCII form and vice-versa.
|
||
|
|
|
||
|
|
|
||
|
|
### 2. Why should I use this instead of [PHP's IDN Functions](http://php.net/manual/en/ref.intl.idn.php)?
|
||
|
|
|
||
|
|
If you can compile the needed dependencies (intl, libidn) there is not much difference.
|
||
|
|
But if you want to write portable code between hosts (including Windows and Mac OS), or can't install PECL extensions, this is the right library for you.
