Running Problems
================
* Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
handled correctly.
-----
Of course, there might be bugs in FreeType, but some fonts based on
the PostScript format can't behandled indeed. The reason is that
FreeType doesn't contain a full PostScript interpreter but applies
pattern matching instead. In case a font doesn't follow the standard
structure of the given font format, FreeType fails. A typical example
is Adobe's `Optima' font family which contains extra code to switch
between low and high resolution versions of the glyphs.
It might be possible to patch FreeType in some situations, though.
Please report failing fonts so that we investigate the problem and set
up a list of such problematic fonts.
