Issues of TTF artifacts

Question

davidxuang opened this issue 5 months ago · comments

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.
