Decodes a character string that was encoded by Encode.
Example
// Encode an image in base64
Res is string = Encode(fLoadBuffer("MyImage.jpg"), encodeBASE64)
// ...
// Decode the image
DecodedImage is Image = Decode(Res, encodeBASE64)
// Decode a buffer received in an HTTP request
bufRead is Buffer = HTTPResponse.Content
<COMPILE IF ConfigurationUnicode>
 	bufResult = Decode(AnsiToUnicode(bufRead), encodeBASE64) 
<ELSE>
 	bufResult = Decode(bufRead, encodeBASE64) 
<END>
Syntax
<Result> = Decode(<Element to decode> [, <Encoding/decoding format>])
<Result>: Character string or Buffer
Result of decoding.
<Element to decode>: Character string
Data to decode. This data was encoded by Encode.
Please note: The string to be decoded must have the same format as the project's default strings: ANSI or Unicode.
<Encoding/decoding format>: Integer constant
Specifies the type of encoding. This parameter must be the same as the one used when encoding.
encodeBASE64
(Default value)
BASE 64 format (complies with the RFC 4648 standard). Encoded text contains only printable characters and CRs (Carriage Returns).
encodeBASE64NoCRBASE 64 format (complies with RFC 4648 standard) without RCs (Carriage Returns). The encoded text contains printable characters only.
encodeBASE64URLBASE 64 URL format (complies with the RFC 4648 standard). The encoded text contains printable characters only.
encodeBASE85BASE 85 format. The encoded text contains printable characters only.
AndroidAndroid Widget Unsupported format.
encodePCSASCII format. The encoded text contains printable characters only.
AndroidAndroid Widget Unsupported format.
encodeURLToAnsiURL format. The encoded text only contains characters allowed in a URL. The decoded text is an ANSI string. This constant corresponds to the encodeURLFromAnsi constant used in Encode.
encodeURLToUnicodeURL format. The encoded text only contains characters allowed in a URL. The decoded text is a Unicode string. This constant corresponds to the encodeURLFromUnicode constant used in Encode.
encodeURLToUTF8URL format. The encoded text only contains characters allowed in a URL. The decoded text is a UTF-8 string. This constant corresponds to the encodeURLFromUTF8 constant used in Encode.
encodeUUEncodeUUEncode format. The encoded text contains printable characters only.

Remarks

Format of character strings to decode

The string to be decoded must be of the same format as the default strings in the current project configuration: ANSI or Unicode.
To know or modify the default string format:
  1. Display the description window for the current configuration: in the "Project Explorer" pane, display the "Configurations" context menu and select "Description".
  2. The "Unicode" tab allows you to know which type of character strings is used by default.
