Remarks

Result of string conversion

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

If a confusion occurs between a string in UNICODE format and a string in ANSI format, the conversion will be implicitly performed.

See Managing the UNICODE format for more details.

UTF8 - ANSI conversion

To convert an ANSI string into a string in UTF8 format, use StringToUTF8.

To convert a UFT8 string into a string in ANSI format, use:

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

Conversion to PHP

The conversion performed in PHP is using the following PHP extensions:

the php_iconv.dll extension
the php_mbstring.dll extension

If none of these PHP extensions is found, only the Latin characters will be converted (the Chinese or Russian characters will not be converted for example).

The php_iconv.dll and php_mbstring.dll extensions are currently proposed on the PHP servers. To find out whether these extensions are proposed by your hosting company, enter the following information in a search engine: phpinfo <Name of hosting company>.

To install these extensions on your own PHP server, all you have to do is uncomment the requested extension in the PHP.INI file.
