The VT100 code page is a character encoding used to represent text on the Classic Mac OS for compatibility with the VT100 terminal. It encodes 256 characters, the first 128 of which are identical to ASCII, with the remaining characters including mathematical symbols, diacritics, and additional punctuation marks. It is suitable for English and several other Western languages. It is similar to Mac OS Roman but includes all characters in ISO 8859-1 except for the currency sign (which was superseded by the euro sign), the no-break space, and the soft hyphen. It also includes all characters in DEC Special Graphics (code page 1090), except for the new line and no-break space controls. The VT100 encoding is only used on the VT100 font on the Classic Mac OS and is not an official Mac OS character encoding.[1]

- ↑ The character 0xCA is the replacement character, which is displayed as a reversed question mark in this encoding.
- ↑ Before Mac OS 8.5, the character 0xDB mapped to currency sign (¤), Unicode character U+00A4.
- ↑ The character 0xE4 is the horizontal scan line-5, which is unified with U+2500 in Unicode.
