Logo 'ferris' broken on Windows
The ferris glyph `u_F323` looks like this in outline view:

Note that there are multiple overlying outlines. Probably it was colored before. The multiple outlines are usually not a problem with `svg`s, but fonts are a bit more picky.
Anyhow, it looks good in `fontforge`'s preview/render mode:

If this is used with the font, it renders correctly on Linux, but there is a problem with the windows font rendering engine:

The 'face' is rendered transparent, because it is two overlaying outlines.

The 'face' ellipsis should probably be removed.

At least it seems to be intended to have no 'face':
