1 This file describes various problems that have been encountered in
2 compiling, installing and running FreeType 2. Suggestions for
3 additions or other improvements to this file are welcome.

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

35 * I get an `internal compilation error' (ICE) while compiling FreeType
38 This has been reported for the following compiler version:
40 Intel(R) C++ Compiler for 32-bit applications,
41 Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
45 The best solution is to update the compiler to version
47 Intel(R) C++ Compiler for 32-bit applications,
48 Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
50 or newer. If this isn't feasible, apply the following patch.
