Direction of shapes? What matters is the code and symbol combination. The rest is just a presentation choice.

What do you mean with "managed"? Anyway, it doesn't mean that the control codes are part of a character set. Control codes are not characters.

The arrangement of the data in the memory. It goes from left to right, not from top to bottom.

In the ROM you mean? Sure, but as I said, the presentation doesn't matter.

So why do you want to change it?

Fwiw my opinion is that reading left-to-right then top-bottom (row major) is the most logical order, because it matches normal reading. I can read the column major version equally well though.

p.s. The topic kinda reminds me of this video, although I like that channel a lot, the ordering they use in that video is the worst (column-major with the origin at the bottom right). That was actively hindering understanding.

The Hotbit 1.1 has just a single character that's different from the Hotbit 1.2 and Expert 1.1: It's the 9Eh character, the useless Cruzado monetary symbol "Cz". So I would also recommend to just discard this charset.

The only real Frankenstein of the group is the Expert 1.0. Gradiente created a proprietary charset (just a mod of the international charset) without consulting anyone. I can't remember of any software that was specific for this machine, and it showed garbage characters for any Portuguese texts and software. As a result, Gradiente offered an "1.1 upgrade kit" that was composed of a new ROM and replacement keys for the keyboard, so very few pure 1.0 machines still exist.

But, if I understood correctly, the intention of the Retro Computers Unicode project is to be able to represent characters available at the legacy computers, right? This would solve problems like this page has, where plenty of PETSCII characters can't be represented on the page.

AFAIK, all of the Expert 1.0 characters can be represented by chars from the MSX-BR charset, or the MSX-international charset, IMHO it's not necessary to create a specific charset for this machine.

I second this. Expert 1.0 charset is useless. Cruzado's symbol "Cz" is also useless. No one needs them.

If you split the control codes from the characters, you may find room for the character at 0x7f... Running Naked in a Field of Flowers

I see you did include it in the font article... I think you're still not making the proper distinction between font and character set....
