New diagonals, octants, sedecimants & eights, separated quadrants & sextants, segmented digits, and large type pieces (Symbols for Legacy Computing)

Added diagonals U+1FB3C - U+1FB67
Added octants (2×4 mosaics) U+1CD00 - U+1CDE5
Added sedecimants (4×4 mosaics) U+1CE90 - U+1CEAF
Added eights (8×8 patterns) U+1FB70 - U+1FB80, U+1FB82 - U+1FB8B
Added misc. blocks U+1FB97, U+1FBCE, U+1FBCF
Added separated quadrants (2×2) U+1CC21 - U+1CC2F
Added separated sextants (2×3) U+1CE51 - U+1CE8F
Added segmented digits (LED/LCD display style) U+1CCF0 - U+1CCF9
Added large type pieces (see #709) U+1CE1A - U+1CE50

This update does not modify any existing character, it is only adding new characters from the Symbols for Legacy Computing blocks (original and supplement). These characters use the same unified coordinates as my previous #708 submission. It continues the sextants with diagonal fills that meet the sextants corners, adds octants, most of the 8×8 pixels-based lines and fills (sedecimants & eights), as well as the separated mosaics, segmented digits, and large type pieces. Some existing mosaic characters are not perfectly aligned on the same grid, and it would be best to adjust them to fit the unified grid as well, but that is not part of this PR, and I guess we won't have the time to do that for the next release.

Note it does not complete the original Symbols for Legacy Computing block yet, as it does not include the extra lines/box-drawing characters, shaded mosaics, MouseText, and some other specific symbols. The focus has been on completing the mosaics part, including the ones coming in Unicode 16.0, and the Large Type Pieces.

This one is quite big, containing almost all the glyphs I've been working on at once. This is to meet the short deadline for the next release of Cascadia Code, as discussed with @aaronbell. It contains 948 glyphs for 479 characters.

Many of the glyphs are pure geometric shapes with no artistic liberty at all, they simply follow the unified grid and handle both GDI and DWrite ("stypo") variants.

All the glyphs have been added to the features.fea::@NotSpace list of non-italic fonts, except for the segmented digits, which have been added to @Digit instead of @NotSpace.

The segmented digits U+1CCF0 - U+1CCF9 are based on their original Atari ST design and Unicode reference design, with the bounding box and segments widths adjusted to fit the H character, and spaces between the segments large enough to be visible even at 12pt on 100% DPI.

The Large Type Pieces are based on their original HP 2640 Series terminals design and Unicode reference design, but I took liberties to reinterpret the pieces to make them more rounded and, I believe, more in line with the Cascadia Code design. Note the Unicode reference design is somewhat wrong as their diagonals do not join perfectly, while my version takes great care to support all the combinations alignments with straight diagonal lines. The only piece where more artistic liberty is available is the Q stem U+1CE45, where I tried to make it more reminiscent of Cascadia's Q design.

More details and screenshots of the large type pieces are available in issue #709.

Finally, U+1FB97 is the same pattern as U+1CDB7, they have different origins, but I'm not sure why Unicode repeated it for octants instead of reusing the existing one as they did for some other existing pattern. I included them as separate glyphs as well.

Continues #708
Improves #715 (does not close it, but greatly improves coverage)
Improves #597 (does not close it, but greatly improves coverage)
Closes #711
Closes #709

Many of the glyphs are pure geometric shapes with no artistic liberty at all, they simply follow the unified grid and handle both GDI and DWrite ("stypo") variants.

All the glyphs have been added to the features.fea::@NotSpace list of non-italic fonts, except for the segmented digits, which have been added to @Digit instead of @NotSpace. @aaronbell, please check if this is what you expect for those or if @Digit is only for the standard digits.

The segmented digits U+1CCF0 - U+1CCF9 are based on their original Atari ST design and Unicode reference design, with the bounding box and segments widths adjusted to fit the H character, and spaces between the segments large enough to be visible even at 12pt on 100% DPI.

The Large Type Pieces are based on their original HP 2640 Series terminals design and Unicode reference design, but I took liberties to reinterpret the pieces to make them more rounded and, I believe, more in line with the Cascadia Code design. Note the Unicode reference design is somewhat wrong as their diagonals do not join perfectly, while my version takes great care to support all the combinations alignments with straight diagonal lines. The only piece where more artistic liberty is available is the Q stem U+1CE45, where I tried to make it more reminiscent of Cascadia's Q design. More details and screenshots of the large type pieces are available in issue #709.

Finally, U+1FB97 is the same pattern as U+1CDB7, they have different origins, but I'm not sure why Unicode repeated it for octants instead of reusing the existing one as they did for some other existing pattern. I included them as separate glyphs as well.

Thanks @DHowett !

Here is a file to cat that demo and explains how the large type pieces work: Edit: Removed embedded file, replaced by github repo, use: curl https://raw.githubusercontent.com/PhMajerus/Documents/main/HowTos/HowTo%20Large%20Type%20Pieces.txt

As well as a FIGlet font that makes using the large type pieces easy: Edit: Removed embedded file, replaced by github repo, see phm-largetype in my FIGfonts collection

I haven't decided how to publish those yet, but figured you may want some more test files.

DHowett commented 2 months ago

THIS IS SO GOOD

I legitimately wonder if the HowTo file should be in this repo, as a sample or a doc. :O

PhMajerus commented 2 months ago

@DHowett I realized I posted the wrong FIGfont. Download it again to get the proper one that uses large type pieces. Sorry about that.

DHowett commented 2 months ago

@aaronbell poke! I didn't want to merge this without your explicit signoff on the artistic direction (e.g. using curves instead of angles for the large type pieces) and thewhether the legacy computing digits should be considered digits qua digits, or just nonspacing characters.

Did you ever hear the Tragedy of Spring Break when one has young children? I thought not. It's not a story the Breakers would tell you.

(This week has been a total bust. Will take a look)

Ugh, sorry about that! ☹️

FWIW, since we are preparing a servicing update for Windows Terminal 1.19/20/21 I'm going to cut a release of it mid-week. I will merge without Aaron's approval late Tuesday under the assumption that we're A-OK to launch :)

aaronbell commented 2 months ago

Hey, I'm sorry. It has been a rough week.

So I'm generally fine with how these things are designed. Personally, I'd probably round some of the curved elements more to make the transitions render more smoothly, buuuuut when I open the UFOs locally in Glyphs, it is requesting that I update the positioning of things (because Glyphs' functionality has updated) and I don't really want to potentially mess with the font right now.

Would it be alright to leave it as is for now, and I'll make some modifications with the next version?

@aaronbell

I wanted to have them even more rounded and achieve the following look:

But remember these are made up of pieces, so the middle horizontal bar has to be straight because it can be used to join two sharp corners or two rounded corners (or any other combination):

Take the 'B' for example:

This is the most I could achieve having the rounding only in the top right corner piece, which is literally just an arc joining the two straight lines it may connect to:

The only solution I could find to round it more is to use ligatures, which then replaces sequences of two or three pieces horizontally with one designed to make the arc reach the middle of the central pieces:

Notice how the arcs are not the same between the exploded view and the combined view anymore.

The ligatures trick works pretty well, and I could achieve the look I aimed for without having them break other combinations (I'm testing with a FIGfont containing over 1000 characters built using large type pieces covering latin, greek, cyrillic, japanese katakana, ...).

Here are the ligatures I worked on so far:

I also tested some other pieces sequences, but these ended up either making it worse, or inconsistent with some other letters using the same combinations in a row:

So yeah, I agree with you more rounded looks even better, and I started working on it using ligatures, but I figured we need a no-ligatures version first as a baseline for Cascadia Mono and then we need ligatures to only improve them without changing the style completely for Cascadia Code. And I didn't want to bother you with the ligatures stuff at this point and figured we could look into that for Cascadia Next/Reboot.

I also didn't know if you'd want to have that many ligatures just to improve the look of the large type:

And there is a problem when using these ligatures in Windows Terminal, I suspect they round up the starting x position of each character, so when my ligatures group three characters into a wider one, they don't always align correctly with other rows at certain sizes:

So I didn't want to make it look worse in some scenario.

If you want to try out my ligatures experiments, here is a version of Cascadia Code that includes them: CascadiaCode with Large Type Pieces ligatures.zip Note it doesn't include all the ligatures I wanted yet, but it gives a good idea of the look and covers the most common cases.

Thanks for the additional information! I think let’s just keep it simple for now and we can revisit it the future.

DHowett commented 2 months ago

Hey, I'm sorry. It has been a rough week.

No need to apologize - I didn't mean to put on any undue pressure. I hope your next week is an improvement on the last one 🙂
