Conversion result

The result of the conversion is a UNICODE buffer. This buffer can only be handled by variables and functions that support UNICODE.
For more details on Unicode, see Managing UNICODE.

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.
