Simply put, The URLs containing the following characters need to be encoded with % (percent symbol) followed by two hexedecimal letters representing 8 bits. URL Encoding works like this - It first converts the character to one or more bytes. To map the wide range of characters used worldwide into the 60 or so allowed characters in a URI, a two-step process is used: For example, the string: François ,would be encoded as: Fran%C3%A7ois If you opt for the ASCII character encoding table, a warning message will pop up if the URL encoded/decoded text base64.cpp and base64.h: The two files that are required to encode end decode data with and from Base64. When decoding, if an invalid hex sequence is encountered (eg "%az" ), it is copied as-is.
