URL decode 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: Convert the character string into a sequence of bytes using the UTF-8 encoding. Convert each byte that is not an ASCII letter or digit to %HH, where HH is the hexadecimal value of the byte.
URL encode RL encoding stands for encoding certain characters in a URL by replacing them with one or more character triplets that consist of the percent character " % " followed by two hexadecimal digits. The two hexadecimal digits of the triplet(s) represent the numeric value of the replaced character.
