Please consider that:
Some data (like URLs) can be sent over the Internet using the ASCII character-set. Since data often contain characters outside the ASCII set, so it has to be converted into a valid ASCII format.
To find it yourself, you can visit https://en.wikipedia.org/wiki/ASCII, there you can find big tables of characters. The one you are looking is in Control Characters

The Hex
is represented with
