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.

Unicode C++

#include <CkStringBuilderW.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    //  This is the URL encoding of the windows-1252 representation.
    const wchar_t *nameWindows1252UrlEncoded = L"M%C6RSK";

    //  This is the URL encoding of the utf-8 representation.
    const wchar_t *nameUtf8UrlEncoded = L"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.
    CkStringBuilderW sb1;
    success = sb1.DecodeAndAppend(nameWindows1252UrlEncoded,L"url",L"windows-1252");

    CkStringBuilderW sb2;
    success = sb2.DecodeAndAppend(nameUtf8UrlEncoded,L"url",L"utf-8");

    //  sb1 and sb2 both hold the same string.
    bool bEqual = sb1.ContentsEqualSb(sb2,true);
    wprintf(L"bEqual = %d\n",bEqual);

    //  We can see the string is "MÆRSK" in both cases.
    wprintf(L"%s\n",sb1.getAsString());
    wprintf(L"%s\n",sb2.getAsString());
    }
