Unicode URL Encoder

URL encoding, is a method to encode arbitrary data in a Uniform Resource Identifier (URI) using only the limited US-ASCII characters legal within a URI. Standard encodes only the characters that are unsafe in a URI, so Hello, World! becomes Hello%2C%20World%21 . All Characters percent-encodes every character, dots and letters included, turning a.b into %61%2E%62 . Unicode uses the non-standard %uXXXX form, so a.b becomes %u0061%u002E%u0062 .
