  • In OS_2 table, The TTFs has Win Ascent of 545 and Win Descent of 1, which is different from Typo Ascent of 500 and Typo Descent of 0 (which is aligned to hhea table), causing some platforms (Windows App SDK, for example) to render the font with additional space on the top. Is this desired behavior?
  • Since 16 is not a factor of 500 (units per em), circles in size16 icons are mostly broken. Haven't found in other sizes but they could be broken too.

20 is a factor of 500 so maybe it's not? You may use FontForge to check if the circles are identical in the TTF.
