Decode from Binary Encoding and Append String

Demonstrates how to decode from a binary encoding (base64, hex, url, etc.) and then append the decoded string to a Chilkat StringBuilder object.

Note: This example uses the new DecodeAndAppend method added in Chilkat v9.5.0.87.

Procedure ChilkatExample()

    ; We have the string "MÆRSK" in two forms:

    ; This is the URL encoding of the windows-1252 representation.
    nameWindows1252UrlEncoded.s = "M%C6RSK"

    ; This is the URL encoding of the utf-8 representation.
    nameUtf8UrlEncoded.s = "M%C3%86RSK"

    ; Note that the result of loading a string into a string object 
    ; is the same if we correctly specify the underlying charset encoding.
    ; In the above example, we have the same string, but in different charset encodings
    ; subsequently URL encoded.
