\begin_layout Standard
XeTeX works with 8-bit fonts for 
\begin_inset Quotes eld
\end_inset

utf8
\begin_inset Quotes erd
\end_inset

 and 
\begin_inset Quotes eld
\end_inset

ascii
\begin_inset Quotes erd
\end_inset

 input encodings.
 There are, however, a number of incompatibilities, because the combination
 XeTeX+TeX-fonts is rarely used and some packages wrongly test for XeTeX
 instead of fontenc.
