Yes there is. You get nonsense for various non-ascii chars if you
use T1-encoding with the unicode engines, and that has nothing to do
with fontspec or font formats. T1 (or OT1) simply don't fit to the
unicode input. 

Try e.g. this with lualatex or xelatex:


hyphenation can be wrong to, as it assumes unicode with the unicode

With the unicode engines you should use TU for the text. If you want
to use a T1-encoded font, one should stick to pdflatex. ttf-fonts
can be prepared for this engine too (with a bit more work).
