Conversion in PHP

The conversion in PHP uses the following extensions:
  • the php_iconv.dll extension
  • the php_mbstring.dll extension
If none of these PHP extensions are used, only Latin characters will be converted (e.g., Chinese or Russian characters will not be converted).
The php_iconv.dll and php_mbstring.dll extensions are currently proposed on PHP servers. To find out if your hosting provider offers these extensions, simply enter the following information in a search engine: phpinfo <Hosting provider>.
To install these extensions on your own PHP server, simply uncomment the desired extension in the PHP.INI file.
