FILLED glyphs = just all ranges of Latin and 'symbols' alike to this day…
vs
EMPTY glyphs =
• U+0020 (" "): Space
• U+00A0 (" "): No-Break Space
• U+2800 ("⠀"): Braille Pattern Blank

EDITABLE =
You can e.g.
• extend (add more Unicode ranges)
• discard some selected codepoints
• stretch to 1x2+ (automatically…)
• add some spacing (width & line?)
• repair the following problem(s):

I am not satisfied at all with the flawed display in my old Microsoft Word: at size 1, the lines seem to be 1.x pixels tall (not 1 on the dot, the expected integer I chose). The buggy outcome is a quite ugly line height of 2 pixels repeatedly here and there (they may change when a line is added before).

Why and how can we fix this pitiful software rendition? (I wasted my time on this, then no update is planned beforehand.)
[If you already fonstructed this kind of n00b pseudo-font without such errors, you can link me to a clonable example (is "Blocksum" applicable?) so that I can get the issue, even fix it myself, else a straightforward genuine bitmap font could work better than its difficult vector imitation. TIA.]

It seems that my oldie MS Word breaks the lines with my fontstructions (either deleted, or added)… I'll try and fix later (esp. if the bug is local).

Here is a screenshot that should give you an idea of the 'degradation'.

On the right the image is turned into in 1 bitplane (B&W w/o gray). The "1x1 filler" pseudo-font would produce a similar look: quite antique (1 pixel = 1 character, period!), yet ultra crisp and economical/portable.

PS more possibilities as e.g. 2x2.
