<Buffer type>.AnsiToUnicode (Function)

In french: <Type Buffer>.AnsiVersUnicode

Converts a buffer containing an ANSI string (Windows) to a buffer containing a UNICODE string.

Reminder:

ANSI is the character set used in Windows.
UNICODE is a character encoding standard. UNICODE is used to manage different languages and character sets.

Example

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

Syntax

<Result> = <Buffer>.AnsiToUnicode([<Charset>])

<Result>: Buffer

Buffer containing a UNICODE string.
EOT if a conversion problem occurred.

<Buffer>: Buffer

Buffer containing an ANSI string to convert. If <Buffer> contains a UNICODE string, <Result> will contain an invalid string.

<Charset>: Optional Integer constant

Character set that will be used for the conversion.
charsetAnsi Roman characters in ANSI standard.
charsetArabic Arabic characters.
charsetBaltic Baltic characters.
charsetChinese Chinese characters (People's Republic of China).
charsetCurrent

charsetUTF8 Used to manage UTF-8 (used in XML, for example).
charsetVietnamese Vietnamese characters.

Remarks

Conversion result

The result of the conversion is a UNICODE buffer. This 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:

the UTF8ToString function.
the UTF8ToAnsi function.

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.
