# TI calculator character sets

In computing, a character set is a system of assigning numbers to characters so that text can be represented as a list of numbers (which are then stored, for example, as a file). For example, ASCII assigns the hexidecimal number 41, or 65 in base 10, to "A". As part of the design process, Texas Instruments (TI) decided to modify the base Latin-1 character set for use with its calculator interface. By adding symbols to the character set, it was possible to reduce design complexity as much more complex parsing would have to have been used otherwise.

## TI-86

The TI-86 character encoding aligns with the ASCII printable characters, but includes its own characters in place of the C0 control codes and 0x7F, as well as defining its own characters in the 0x80 to 0xFF range (which is not part of ASCII).

## TI-89/92 Series

The TI-89/92 Series calculators use a character encoding similar to Latin-1, except that most of the control characters are replaced with mathematical symbols or Greek letters. All characters are printable except the null character.
