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
