Example

MyAnsiBuffer is Buffer
// Convert the MyUnicodeBuffer buffer
// that contains a UNICODE string
// to a buffer containing an ANSI string
MyAnsiBuffer = UnicodeToAnsi(MyUnicodeBuffer)

MyUnicodeString is UNICODE string
MyAnsiString is string
FileNum is int = fOpen("c:\Temp\MyText.txt", foRead + foUnicode)
IF FileNum <> -1 THEN MyUnicodeString = fReadLine(FileNum)
MyAnsiString = UnicodeToAnsi(MyUnicodeString, charsetGreek)

MyAnsiBuffer is Buffer
// Convert the character string
// MyString in UNICODE format
// to a buffer containing an ANSI string
MyAnsiBuffer = UnicodeToAnsi(MyString)

Remarks

UTF-8 and ANSI conversion

UTF8ToString.

UTF8ToAnsi.
New in version 18

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.
