The point too is the font is very small on these Acer Swift when
nothing is installed, and as I am a bit old I have difficults to see
characters...
Have you tried experimenting with different font faces?
# dkpg-reconfigure console-setup
Different faces permit different sizes, which you can read about[1] in
$ man 5 console-setup
under OPTIONS, in the section on FONTFACE and FONTSIZE:
| FONTFACE and FONTSIZE
| Valid font faces are: VGA (sizes 8x8, 8x14, 8x16, 16x28 and 16x32),
| Terminus (sizes 6x12, 8x14, 8x16, 10x20, 12x24, 14x28 and 16x32),
| TerminusBold (sizes 8x14, 8x16, 10x20, 12x24, 14x28 and 16x32),
| TerminusBoldVGA (sizes 8x14 and 8x16), and Fixed (sizes 8x13, 8x14,
| 8x15, 8x16 and 8x18). If however CODESET=Ethiopian, then the
| available font faces are Goha and GohaClassic, each in sizes 8x12,
| 8x14 and 8x16.
I don't know about your particular device, but FWIW the Terminus
fontface frequently proves helpful for me.
