I have a $10 purchase but the option is unavailable :/ sent a bug report in case it's a bug

i think the base size is 8
well, i used fontdrop, and at 8 it shows the font at 1x scale, so i'm pretty sure that's the right number

actually FontForge has an option to view unicode ranges
just gotta download it, open the font and go to Element > Font Info > Unicode Tables

i lost the original unicode tables i was using a long while ago because i thought i wouldn't need them again 😅 
i tested out [otfinfo -u Pizel.ttf > output.txt] on linux and it might help you. though it lists all the symbols 1 by 1 instead of symbol ranges, resulting in 2227 lines... maybe it could be done with some other script. i could also send you the output file if you don't have the means to use the tool.
you could also try the online tool FontDrop, though i don't really know how to parse its outputs
