Atari ST character set

The following table shows the Atari ST character set. Each character is shown with a potential Unicode equivalent if available. Differences from code page 437 are shown boxed.

Although the ROM provides a graphic for all 256 different possible 8-bit codes, some APIs will not print some of these code points, in particular the range 0–31 and the code at 127. Instead they will interpret them as control characters.

Using Alt codes, users can enter a character by holding down the Alt key and entering the three-digit decimal code point on the Numpad. This provides a way to enter special characters not provided directly on the keyboard.

The Atari ST character set long predates the introduction of the euro currency and thus does not provide a code point for the euro sign (U+20AC, €). However, some software (such as Calamus) utilizes code point 238 (0xEE) for this purpose. This code point is normally assigned to the mathematical element-of sign (U+2208, ∈), and to the Greek lowercase epsilon (U+03B5, ε) in code page 437.

Alternatively, the rarely used logical conjunction sign (U+2227, ∧) at code point 222 (0xDE) could be replaced by the euro sign.
