Unscii is a set of bitmapped Unicode fonts based on classic system fonts. Unscii attempts to support character cell art well while also being suitable for terminal and programming use.

The two main variants are unscii-8 (8×8 pixels per glyph) and unscii-16 (8×16). There are also several alternative styles for unscii-8, as well as an 8x16 "full" variant that incorporates missing Unicode glyphs from Fixedsys Excelsior and GNU Unifont. "unscii-16-full" falls under GPL because of how Unifont is licensed; the other variants are in the Public Domain.

Unscii was created by Viznut.


In 2020-03-10, the new Unicode version 13.0 added 214 graphics characters for "legacy computing" (including, among all, the missing PETSCII characters, and a majority of missing Teletext/Videotex characters). Most of these were already included in Unscii 1.x, but now I have been able to give them proper Unicode mappings as well. This is the main reason for the Unscii 2.0 release.

Additionally, Unscii 2.0 fixes errors in some characters, legibility in some others and adds a bunch of new ones.

Here are some conversions of legacy character set art into Unscii.

Amiga ansi: Divine Stylers by Hellbeard, as rendered with unscii-16. Source

PC ansi: Ansi Love by Rad Man, as rendered with unscii-16. Source

Commodore 64 petscii pictures as rendered with unscii-8, using the 256-color xterm palette: I Has Floppy by Redcrab; The First Ball by Dr.TerrorZ; Gary by Mermaid.

The source code package includes a generic bitmap-to-unscii converter. Here's an example of a conversion to unscii-8 using the 256-color xterm palette, without dithering:


HEX and PCF are the only actual bitmapped formats here. HEX is the same simple hexdump format as used by the Unifont project. TTF, OTF and WOFF are vectorized.

NOTE: Due to format limitations, the PCF versions lack all the characters above U+FFFF! However, all the new graphics characters are provided in the good old PUA range as well. A mapping is in the file uns2uni.tr.

[Some Unscii16 glyphs]

unscii-16: hex pcf ttf otf woff
unscii-16-full: hex pcf ttf otf woff
8x16. The latter is recommended for serious terminal use where a large Unicode coverage is needed. (Warning: unscii16-full files range from 2 to 12 megabytes in size; the others range from 40 to 400 kilobytes.)

[Some Unscii8 glyphs]

unscii-8: hex pcf ttf otf woff

[Ascii range in Unscii8-tall

unscii-8-tall: hex pcf ttf otf woff
Double-height version of unscii8.

[Ascii range in Unscii8-tall

unscii-8-thin: hex pcf ttf otf woff
Based on system fonts with 1-pixel-wide lines.

[Ascii range in Unscii8-alt

unscii-8-alt: hex pcf ttf otf woff
Based on the more peculiar glyph forms of the reference fonts.

[Ascii range in Unscii8-alt

unscii-8-mcr: hex pcf ttf otf woff
Based on retrofuturistic MCR-like 8×8 fonts used in various games, demos, etc.

[Ascii range in Unscii8-alt

unscii-8-fantasy: hex pcf ttf otf woff
Based on fonts used in fantasy games.

Years ago, I noticed that Unicode had a bunch of pseudographic characters that could be used to enrichen Ansi art. However, no one seemed to use them. Even MUDs that used the 256-color Xterm palette and had no issues with Unicode still preferred to stick to the blocks available in the MS-DOS codepage 437.

After looking into existing Unicode fonts, the reason became obvious: the implementation of non-CP437 graphics characters was shaky at best. Unicode Consortium doesn't even care how pseudographics are implemented. It was a kind of chicken-and-egg problem: No commonly accepted Unicode graphics font, no Unicode art scene; no art scene, no font support. The idea of an art-compatible Unicode font was born.

For Unscii, I studied a bunch of classic system fonts and how their characters had been used in Ascii and "extended-Ascii" art.

8×8 system fonts can be divided in two major categories according to their line thickness: 1-pixel and 2-pixel. 2-pixel-wide lines are used in more prominent classic systems, so I chose it. Also, 2-pixel 8×8 system fonts are surprisingly similar to one another which made it easier to choose neutral shapes.

The basic look of the 8×8 variant of Unscii is based on the following systems:

The 8×16 variant of Unscii has been mostly derived from the 8×8 variant by using a set of transformation principles. When in doubt, the following fonts have been looked at for additional reference:

In general, neutral shapes are preferred, unless art, legibility or readability require otherwise: The characters /\XY are connective because of their connetive use in ascii art, and the serifs in iIl are longer than in most classic systems.

Whenever a 8×16 shape has not been defined, Unscii falls back to height-doubled 8×8.

I also studied game fonts and thin-line system fonts. This resulted in the variants unscii-8-thin, unscii-8-mcr and unscii-8-fantasy.

When studying legacy character sets, I found literally hundreds of characters without proper Unicode codepoints. These are mapped in the PUA range as follows:

Since Unicode 13.0, many of these are also available in Unicode, but the PUA mappings are retained for compatibility.
