Finished! (Took me 3 days)
Private use characters are encoded in Variation Selectors and Latin Ext. D.
Finally done. Phew! It took two days to make this. This is a full collection of 5×7 Dot Matrix characters as seen on many devices, like Texas Instruments calculators. A lot of these are custom. Sources include TI-83, TI-86, TI-89, Casio Monochrome Graphing Calculators, Casio fx-115ES PLUS, and the rest, I created them myself. I included fractions for those themes on Microsoft Office don't have matching "1/3" and other fractions with the "1/4", "1/2", and "3/4". The fullwidth characters are substitutes for the other characters in the regular style, such as the math "x" and "y" from Casio.
Please note that character sets like Arabic and some Math Operators are beyond 5×7 pixels. If you want to know why? Because Arabic is very big and if I put it all in 5×7 pixels, the text will look weird, won't really fit inside, and there would be no point to it. I left it as is. Roman Numerals cannot fit if you were doing the "VIII" character, for example.
8/28/2019: Font created.
1/7/2020: Added characters in the following form: Fullwidth and Halfwidth are used for making TI-73 Explorer characters, plus actual monospace setting characters. Note that Runic, Tagalog, and Hanunoo are replaced with character variants. The last variation of a character is from Minecraft's font. The fractions are also changed to level the line spacing. The wide "M" is never ever for use on Monospacing.
1/8/2020: More variations are added, extended to replace Buhid. I also added other math symbols and more. To type x̄, press unicode shortcut and type 01b2. To type ȳ, press unicode shortcut and type 01b3. I also added over a hundred, or two hundred, more characters to stock up on the font. Oh and I changed the filters to separate the pixels for a more pixel and retro look. Also fixed the spacing on the "Щ" character.
9/8/2020: Added a bunch of more characters to the font set.
Note that this font is work in progress so you will recieve updates here.
