But as I wrote in my other post fontspec alone didn't trigger the
update of the font database. I had to add some math. Investigating a
bit I found an additional difference: the extension matters.
euenc loads the fonts without extension:

file:lmroman10-regular:script=latn;+trep;+tlig;

And this works fine (as does \font\test=file:arial). But
\font\test=file:lmroman10-regular.otf:script=latn;+trep;+tlig;
  or 
\font\test=file:arial.ttf

triggers again the recreation of the database.

Yes there is no problem in using the fonts. There are all found in
the end. The only problem is the time delay due to the database
updates.
