fontlint fontfile ...
The program fontlint loads a font (or more than one), which may be in any format fontforge(1) can read, and checks the font for certain common errors
* Intersecting contours
* Incorrectly oriented contours
* Extrema not marked by points
And for PostScript fonts:
* Too many points in a glyph
* Too many hints in a glyph
* Bad glyph name
