a pixelated unicode font that can be read at small sizes.

14 sept '22, 17:47:11 hkt / massive update. added coptic, spacing modifier letters and improved readability.

What if GS Unicode wasn't just made of pixels?  What if it had a better, more appealing width/height ratio?  What if it utilized the new FS inventory?  And what if I wasn't way too ambitious/crazy in making this?  No idea, but I'm eager to find out!

I've split this font series up by plane since font files have a technical limit of 65,535 glyphs.

Things that are planned but not fully implemented yet are italicized.

This font (Plane 0) should also serve as the hub for most major updates (like those relating to the series as a whole).

Feel free to recommend PUA assignments!

Also, it's more than likely I won't know every script well enough that there won't be any mistakes.  If/when I make a mistake, please tell me and I'll do my best to fix it!

My take on the Mongolian 'Phags-pa script designed by the Tibetan monk Phagspa in 1269, based on the Tibetan script, to write Mongolian, Tibetan, Sanskrit and Chinese. This font is based on the Tibetan style which consists almost entirely of straight lines and right angles. It seemed like a prime candidate for a FontStruct treatment. I've added rounded corners and serifs to make it more visually interesting.

The script is written in vertical columns top-to-bottom and left-to-right and thus needs to be rotated 90° clockwise and the columns then reversed.

'Phags-pa was added to the Unicode standard in version 5.0 in 2006. This font however uses an ad-hoc mapping to Ascii characters which admittedly doesn't always make sense. I kind of gave up in the end and started assigning a bunch of letters to digits. Letters are connected into syllable block by a thin line (mapped to '-'), usually on the right-hand side. A straight line clashed wth the serifs so I made it into a small arch.

The script is an abugida: the vowel ‹a› is inherent in each syllable and thus not written.
