Remarks

Conversion result

The result of the conversion is a UNICODE string or buffer. This string (or buffer) can only be handled by variables and functions that support UNICODE.

In case of confusion between a UNICODE and an ANSI string, the conversion will be implicitly performed.

For more details on Unicode, see Managing UNICODE.

UTF-8 and ANSI conversion

To convert an ANSI string to UTF-8, use StringToUTF8.

To convert a UFT-8 string to ANSI, use:

UTF8ToString.
Versions 18 and later
UTF8ToAnsi.
New in version 18
UTF8ToAnsi.
UTF8ToAnsi.

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.
