URL Encode and Decode from Clipboard

Use this tool from above to either encode or decode a string of text.

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
For example, the string: François ,would be encoded as: Fran%C3%A7ois

(The "ç" is encoded in UTF-8 as two bytes C3 (hex) and A7 (hex), which are then written as the three characters "%c3" and "%a7" respectively.) This can make a URI rather long (up to 9 ASCII characters for a single Unicode character), but the intention is that browsers only need to display the decoded form, and many protocols can send UTF-8 without the %HH escaping.
