AutoIt

Demonstrate the Global.AutoQBDecode property

The Global.AutoQBDecode property can be set to _TRUE_ to cause Q/B encoded string arguments passed to any Chilkat method to be automatically decoded before being used.

Note: This example requires Chilkat v10.0.0 or later.

AutoIt

;  Turn on auto Q/B decoding for all strings passed to any Chilkat method in any Chilkat class.
$oGlob = ObjCreate("Chilkat.Global")
$oGlob.AutoQBDecode = True

;  "Q" Encoding

;  Quoted-Printable encoding is primarily used for text that is mostly ASCII with some non-ASCII characters. 
;  It encodes these characters in a way that remains mostly readable and compatible with ASCII-only systems.

;  How It Works with UTF-8:
;  - ASCII characters (except special characters like `=`) are encoded as themselves.
;  - Non-ASCII characters are represented by their UTF-8 byte values, each byte encoded as `=` followed by two hexadecimal digits. 
;    For example, the UTF-8 character "é" (U+00E9) is encoded as `=C3=A9`.

;  For example, consider the text "Café" encoded in UTF-8. The UTF-8 bytes for "é" are `C3 A9`, so in Quoted-Printable, it looks like this:  Caf=C3=A9

;  The "Q" encoding has this syntax:  "=?charset?q?encoded_text?="
;  For example: "=?UTF-8?Q?Caf=C3=A9_announcement?="

;  ------
;  "B" Encoding

;  Base64 encoding is used to encode non-ASCII text, making it more suitable for text with a high density of non-ASCII characters, such as those found in non-Western European languages.

;  For example, consider the text "こんにちは" ("Hello" in Japanese).
;  The "B" encoded string would be "=?UTF-8?B?44GT44KT44Gr44Gh44Gv?="

;  ------
;  Q encoding is suitable for text that is mostly ASCII.
;  B Encoding is best for text that is densely packed with non-us-ascii chars, such as non-Latin (Asian) languages.

;  You can use Chilkat's online tool at Online Binary Encoder to pre-encode your literal strings before
;  inserting them into your source code.

;  When using the online tool, choose either "MIME header Q Encoding" or "MIME Header B Encoding".

;  For example:
Local $s_cafe = "=?utf-8?Q?Caf=C3=A9?="
$oS1 = ObjCreate("Chilkat.StringBuilder")
$oS1.Append($s_cafe)
ConsoleWrite($oS1.GetAsString() & @CRLF)
;  Output is Café

Local $s_hello = "=?UTF-8?B?44GT44KT44Gr44Gh44Gv?="
$oS2 = ObjCreate("Chilkat.StringBuilder")
$oS2.Append($s_hello)
ConsoleWrite($oS2.GetAsString() & @CRLF)
;  Output is こんにちは
