Apple II character set
Apple II text mode uses the 7-bit ASCII (us-ascii) character set. The high-bit is set to display in normal mode on the 40x24 text screen.

[edit]The original Signetics 2513 character generator chip has 64 glyphs for upper case, numbers, symbols, and punctuation characters. Each 5x7 pixel bitmap matrix is displayed in a 7x8 character cell on the text screen. The 64 characters can be displayed in INVERSE in the range $00 to $3F, FLASHing in the range $40 to $7F, and NORMAL mode in the range $80 to $FF. Normal mode characters are repeated in the $80 to $FF range.
To display lowercase letters, applications can run in the graphics modes and use custom fonts, rather than running in text mode using the font in ROM.

- ^ Apple uses U+F8FF in the Corporate Private Use Area to display the solid Apple logo. It does not have a Unicode code point and it is usually not supported on non-Apple platforms.
- ^ The left and right "running man"[1] halves were replaced with different characters in the Apple IIGS version of the MouseText character set (shown below.)
Apple IIGS
[edit]Two characters in the Apple II MouseText character set was updated for the GS. The characters unique to MouseText are encoded in Unicode's Symbols for Legacy Computing block.[1][2]
