A character may refer to any of the following:
For example, the letter "A" is a single character. With a computer, one character is equal to one byte, which is 8 bits. A computer can understand a character with ASCII, which defines each character as a number that is translated to binary. For example, the letter "A" is "65" in ASCII and "01000001" in binary.
An invalid character error may be encountered when a character is used that is not supported by the program or operating system. For example, you may get this error when trying to use a non-alphanumeric character or a character with an accent.
See the char definition for a full definition on the char programming term.
How to write a character on a computer
The most common method for a user to write a character on a computer is with the keyboard. Smaller devices like a smartphone that don't use a physical keyboard may use a virtual keyboard. It's also possible to input a character using voice recognition.
For example, while playing a game, you are considered a PC (player character) in that game. If you encounter a character that is not controlled by another human, it is referred to as an NPC (non-player character). The picture is an example of a character in the World of Warcraft game.
