The deficiency is actually with xetex/xdv2pdf's so-called "support" for 
legacy TeX fonts, which is pretty fragile. It tries several fairly 
messy tricks in an attempt to guess the glyph numbers needed to render 
the character codes coming from TeX, via the Quartz glyph-rendering 
APIs, but it's not as robust as I'd like it to be.

I believe it could be fixed if there were a specific encoding file 
associated with Euler in the psfonts.map file that associates tfm names 
with downloadable fonts; someone with sufficient motivation might want 
to give this a try.
