`tv` doesn't use Unicode 13's 2x3 mosaics

[rbanffy]

Since Unicode 13 was released, it's possible to use 2x3 mosaics (as implemented in TRS-80 computers and Teletext terminals) and other characters that could make nicer images.

I can add them to the CHARS constant after the 2x2 characters, but I don't know exactly how the character selection works. We could also use extended smoothed mosaics (also from Teletext) or PETSCII and ATASCII characters added in version 13.

Sorry for the delay (I was on holidays). Thanks for pointing this out, are there any fonts that support these characters yet? I can look into supporting this.

VTE and (I think) QtTermWidget (covers most Gnome and KDE terminals) implement them independently of the font.
