All printable ASCII characters can be entered directly. Those that are not alphanumeric are assigned explicit names in Mathematica, allowing them to be entered even on keyboards where they do not explicitly appear.

In the Mathematica front end, characters entered on the keyboard are interpreted according to the current setting of the CharacterEncoding option for the current notebook.

Codes for characters can be generated using ToCharacterCode. The Unicode standard is followed, with various extensions.
8-bit characters have codes less than 256; 16-bit characters have codes between 256 and 65535. Approximately 750 characters are assigned explicit names in Mathematica. Other characters must be entered using their character codes.
