As you could read last year Unicode Consortium Consortium accepted proposal to add retro computer and teletex characters to Unicode .
On 10th March 2020 new Unicode version 13.0 was released that have 214 graphics characters for “legacy computing” (including PETSCII characters, and Teletext/Videotex characters).
According to Uniscii author Viznut these were already included in Unscii 1.x, but with an Unscii 2.0 release they have proper Unicode mappings,additionally Unscii 2.0 fixes errors in some characters, legibility in some others and adds a bunch of new ones.
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.
There are two main variants are unscii-8 (8×8 pixels per glyph) and unscii-16 (8×16)., but there are also several alternative styles for unscii-8, as well as an 8×16 “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 while the other variants are in the Public Domain.
On picture You see three 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.
