(DataFlex) 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 Test
    String sNameWindows1252UrlEncoded
    String sNameUtf8UrlEncoded
    Handle hoSb1
    Boolean iSuccess
    Variant vSb2

    Boolean iBEqual

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

    // This is the URL encoding of the windows-1252 representation.
    Move "M%C6RSK" To sNameWindows1252UrlEncoded

    // This is the URL encoding of the utf-8 representation.
    Move "M%C3%86RSK" To sNameUtf8UrlEncoded

    // 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.
