// Convert the MyUnicodeBuffer buffer
// that contains a character string in UNICODE format
// into a buffer containing a character string
// in ANSI format
MyAnsiBuffer = UnicodeToAnsi(MyUnicodeBuffer)

MyUnicodeString is UNICODE string
MyAnsiString is string

IF FileNum <> -1 THEN
MyUnicodeString = fReadLine(FileNum)
END
MyAnsiString = UnicodeToAnsi(MyUnicodeString, charsetGreek)

Remarks

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.
