Some of your statements seem wrong or at least confusing to me: Am 2008-03-01 um 13:19 schrieb Roland:
Seems we never posted the conclusion about this problem: XeTeX simply doesn't work with the old Mac Type 1 Postscript fonts on Mac OS X (Leopard or before). The reason is that these old fonts store their data in the resource fork, which Unix utilities like XeTeX don't see. Only TrueType or OpenType fonts will be recognised and loaded correctly.
As you state later, all data fork fonts (TrueType, OpenType and PostScript) should work. For I never tried XeTeX I don't know if PS Type 1 and 3 will work. Isn't it possible to use traditional TeX-installed fonts with XeTeX?
PCs don't have the data fork
PCs don't know the Mac *resource* fork. BTW there are different forks *possible* with NTFS (supported from WinNT to XP, no more in Vista)!
For those with access to a font conversion program like fondu (?) fontforge (?) or fontlab (?) it may be possible to convert the old Type 1 font
fondu is by the same author as fontforge; look at http://fondu.sourceforge.net/ http://fontforge.sourceforge.net/ Greetlings from Lake Constance! Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)
