Converts:
  • a UNICODE string to an ANSI string (Windows).
  • a buffer containing a UNICODE string to a buffer containing an ANSI string (Windows).
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
// Convert the MyUnicodeBuffer buffer
// that contains a UNICODE string
// to a buffer containing an ANSI string
MyAnsiBuffer = UnicodeToAnsi(MyUnicodeBuffer)

Syntax

Converting a Unicode string Hide the details

<Result> = UnicodeToAnsi(<String to convert> [, <Charset> [, <Unknown character>]])
<Result>: String or buffer
ANSI string.
<String to convert>: Unicode string
UNICODE string to be converted. This parameter can also be an ANSI string that contains UNICODE characters.
<Charset>: Optional Integer constant
Character set that will be used for the conversion.
charsetAnsiRoman characters in ANSI standard.
charsetArabicArabic characters.
charsetBalticBaltic characters.
charsetChineseChinese characters (People's Republic of China).
charsetCurrent
Default value
Uses the current character set specified with ChangeCharset (charsetOccidental by default).
charsetDefaultUses the computer's default character set. No character set is forced.
charsetEastEuropeEastern European characters (Polish, etc.).
charsetGreekGreek characters.
charsetHebrewHebrew characters.
charsetJapaneseJapanese characters.
charsetKoreanKorean characters.
charsetMacMac Roman character set (used in previous versions of Macintosh).
charsetOccidentalRoman characters in ANSI standard.
charsetRussianRussian characters.
charsetThaiThai characters.
charsetTraditionalChineseTraditional Chinese characters (Republic of Taiwan).
charsetTurkishTurkish characters.
charsetUTF8Used to manage UTF-8 (used in XML, for example).
charsetVietnameseVietnamese characters.
<Unknown character>: Optional character or constant
Character to use if an unknown character is encountered during the conversion process. The NULL constant allows you to use the default system character.

Converting a buffer containing a Unicode string Hide the details

<Result> = UnicodeToAnsi(<Buffer> [, <Charset> [, <Unknown character>]])
<Result>: Buffer
Buffer containing an ANSI string.
<Buffer>: Buffer
Buffer containing the UNICODE string to be converted. If <Buffer> contains an ANSI string, the result will be undefined.
<Charset>: Optional Integer constant
Character set that will be used for the conversion.
charsetAnsiRoman characters in ANSI standard.
charsetArabicArabic characters.
charsetBalticBaltic characters.
charsetChineseChinese characters (People's Republic of China).
charsetCurrent

UTF-8 and ANSI conversion

To convert an ANSI string to UTF-8, use StringToUTF8.
To convert a UFT-8 string to ANSI, use:
PHP

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.

PARA RESOLVER PROBLEMAS DE ACENTUAÇÃO
Prezados,

Caso de problema com acentuação, use:

retorno is string = UFT8toString(textocomacento)

USE O COMANDO UTF8ToString OU AnsiToUnicode


ProcedureWS_Android_IOS_HTTPGetResult()

// Variable
bufResHTTP is Buffer
sHTTPResult isstring

// Retrieves the result of the query
bufResHTTP=HTTPGetResult(httpResult)

// Result in UTF8 em iOS Apple
IFIniOSMode() =TrueORIniOSSimulatorMode() =TrueORIniOSEmulatorMode() =True
IFStringCount(bufResHTTP, “ISO-8859-1”,IgnoreCase) =0THEN
sHTTPResult=UTF8ToString(bufResHTTP)
ELSE
sHTTPResult=AnsiToUnicode(bufResHTTP)
END
ELSE IFInAndroidMode() =TrueORInAndroidSimulatorMode() =TrueORInAndroidEmulatorMode() =True
// Result in Android
sHTTPResult=bufResHTTP
END
