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.

integer li_rc
integer li_Success
string ls_NameWindows1252UrlEncoded
string ls_NameUtf8UrlEncoded

li_Success = 0

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

// This is the URL encoding of the windows-1252 representation.
ls_NameWindows1252UrlEncoded = "M%C6RSK"

// This is the URL encoding of the utf-8 representation.
ls_NameUtf8UrlEncoded = "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.

// sb1 and sb2 both hold the same string.

Write-Debug "bEqual = " + string(li_BEqual)

// We can see the string is "MÆRSK" in both cases.
