It seems that using an OTF version of a font is not sufficient for
XeTeX to use the fi and fl ligatures.  I converted the Utopia Type1
Font included with MiKTex 2.7 using two different programs:

CrossFont [1] -> Utopia-Regular.otf
TransType Pro [2] -> UTOPIA-R.OTF

The attachment to this email contains both converted fonts, a minimal
example using fontspec's ExternalLocation option, and the resulting
PDF.

Although both fonts are OpenType fonts, only the conversion by
TransType Pro (UTOPIA-R.OTF) makes XeTeX using the ligatures.

As always, Adobe InDesign CS3 automatically uses the ligatures also in
Utopia-Regular.otf.

Kind regards,
Markus
