I have a very strange error. I have a small font that contains just the alphabet. In Fontcreator test all of the glyphs show up perfectly but once I install the font certain glyphs (those with more than 1000 points) don’t show up at all; the space that the glyph takes up is shown but not the glyph itself. This is in all of the (windows) applications including office and as artistic text in graphics packages.
There’s another error and that is that if the glyph was made too small (using the ‘standard’ settings) then it makes the lines VERY thick when expanded so I had to make the glyphs very large when creating them or the glyph is unreadable (just a bunch of overlapping thick lines). So I had to make the font very tall (10,000 rather than just over 1,000).
Font rendering is most likely hardware-accelerated but it is handled by Windows. At some point complex and/or large glyph outlines fail to display. It might work on one system, while it fails on another. Also be aware printer drivers also have limits, so it might be an issue there as well.
In your case I suspect the glyph is too complex for your graphics processing unit, so you might need to simplify the glyph outline and/or make it smaller.
