ok, the first problem is that xetex fails on the test that contest does with regards to 8-bit support; since we may assume that xetex is ok in this respect, you can add to cont-new.tex: 

\beginXETEX
    \let\testbytesequence\empty
\endXETEX

The second problem is more tricky. In pdftex context assumes that natural.tcx is loaded, i.e. ^^M becomes a cr); it looks like xetex is escaping the < 32 chars (it does not support tcx filters not the -8bit flag). If this is indeed true, then we have a problem because we cannot have roundtrip write/read in xetex then. Given the nature of xetes, i'd expect it to be 8 bit clean, evan for < 32 chars.

i can probably cook up a quick fix for mp but i'm sure that in other areas problems will show up
