Use SAIL charset without translation to Unicode #12

Closed larsbrinkhoff closed 6 years ago

larsbrinkhoff commented 7 years ago

Some older devices only support 7 or 8-bit character codes, but have a programmable font store. (I'm thinking primarily VT220 and compatible terminals.)

These devices can enable %TOSAI but does not have to translate the extended ASCII characters to Unicode.

Of course, there's no point in doing this unless there is a font for the extended ASCII charset.

I'm working on such a font. I have a BDF font converted from the Knight TV. But I have to make another which can be used with a VT220.

The terminal will not display the control characters, even though if they have glyphs defined in the font. There would have to be some kind of translation. Probably to codes greater than 217 (octal).
