JIS X 0201 is only single byte characters. Looks like all the standard fonts on the MSX are single byte.

as for the [ and ], load up the title screen and you'll see them displayed in the first text line. They seem to be regular text here. Maybe some other character gets used for it, maybe some command allows them to be loaded? I doubt it's calling end of line, then adding more text to the same line and then doing a line break and loading more text.

What I meant with "same bit" was just that 80-FF are most likely the same. I'll link the font page again: https://www.msx.org/wiki/MSX_font.

Here are the quick notes I made when just trying to load the entire font: https://pastebin.com/trFBK9wG So you have an idea what the "special characters" actually are.

If you follow that font page with what I think has been switched around you can figure out the crashing characters. which might help in finding code snippets. There are some irregularities though. [ and ] for example aren't at 7b or 7d as you'd expect them to be following the logic below, they are at 1a and 1b.

00-7F are different from the one shown there it seems. 86-FF, seem to follow exactly what's on that font chart for Japan.

00-1F now seems to be 20 to 3F, 40-5F has been moved to 60-7F and vice versa for the small font.

Maybe the original 00-1F got moved to 20-3f? They fall within the crash category, so I can't see them.

80-85 are special characters, card deck and 2 circles. They also just crash, so I assume they also get used or are empty?
