What Does Character to Hexadecimal (C2X) Mean?
Character to hexadecimal (C2X) is a conversion of values from character values or strings to an equivalent hexadecimal value, with the character usually encoded in ASCII.

Techopedia Explains Character to Hexadecimal (C2X)
Character to hexadecimal is not actual conversion but simple representation of the corresponding character. This is because a computer can only understand numbers, so characters have to be represented as numbers. In turn, numbers can be converted into other representations in other number systems.
For example, the decimal code for the ASCII character % is 37 in decimal, so its equivalent Hexadecimal value is 25 and its octal value is 045.
