8================

10
11* Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
12 handled correctly.
13
14-----
15
16Of course, there might be bugs in FreeType, but some fonts based on
17the PostScript format can't behandled indeed. The reason is that
18FreeType doesn't contain a full PostScript interpreter but applies
19pattern matching instead. In case a font doesn't follow the standard
20structure of the given font format, FreeType fails. A typical example
21is Adobe's `Optima' font family which contains extra code to switch
22between low and high resolution versions of the glyphs.
23
24It might be possible to patch FreeType in some situations, though.
25Please report failing fonts so that we investigate the problem and set
26up a list of such problematic fonts.

Werner Lemberg1639c792006-05-06 16:44:58 +0000[diff] [blame]35* I get an `internal compilation error' (ICE) while compiling FreeType
36 2.2.1 with Intel C++.

Werner Lembergde2d90a2006-05-17 08:54:30 +0000[diff] [blame]38 This has been reported for the following compiler version:

45The best solution is to update the compiler to version
