1)It's an Arabic ligature thing Unicode stuck in Unicode 2)Where and why did you even find that LOL

Too many bugs (e.g. 'R') and dupes for me (lower case esp.). Perhaps you can improve a bit the Latin chrs ? (as I don't know about the accuracy in the Cyrillic ones). Interesting bilingual font anyway.

You're so right, it's a very tough job to put everything legibily in such a small grid. But a lot of satisfaction afterwards, believe me (though it's even funnier as 3x4 - hundreds of unique glyphs, even plenty of diacritics, even a lot of Cyrillics and special Unicode if you overcome the lowercase dilemma). I hope I was not too harsh in my previous C&C… it's my - bad - way of encouraging you. I know you can improve your micro font a lot ; e.g. see the other FontStructions from the list here :

Thank you. Though there's a lot of 3x3 'competitors', and since your 5Mikroskop got the size record (on FS at least) as a - partial - 2x3 identifiable font (1x2, 2x1 and 1x1 pixel can't), perhaps it is now another task for you to complete (it) too ? (Gr8t US/GB/ZZ synt@X, donT U' LOL!)

Yes, Groszak, I think there are at least two approaches in this field of design :
• Similar chrs (unsafe, yet more legible) ;
• Unique chrs (safe, yet less legible).

E.g. the famous 'I' / 'l' / '1' / '|' ambiguity, that is quickly taken into profit pertaing to 3x3 grids :
_X_
_X_
_X_
… This glyph would stand for all of these chrs, acceptably…

Zoom:

if you use windows, use character map and select character U+0328 (combining ogonek) in lucida sans unicode. if you put this after letter, then will put into letter. Use other combinings too
