C#
bool success = false;

//  To URL encoding a string:
string s = "Why a > b?";

Chilkat.StringBuilder sb = new Chilkat.StringBuilder();
success = sb.Append(s);

//  URL encode the string.
sb.Encode("url","utf-8");

//  Show the URL encoded string:
string sEncoded = sb.GetAsString();
Debug.WriteLine(sEncoded);

//  The result is:  Why%20a%20%3E%20b%3F

//  If you prefer "+" instead of "%20" for SPACE chars:
int numReplaced = sb.Replace("%20","+");
Debug.WriteLine(sb.GetAsString());

//  Output is:   Why+a+%3E+b%3F

//  To decode:
sb.Decode("url","utf-8");
Debug.WriteLine(sb.GetAsString());

//  Result is: Why a > b?
