universal character name

[Patrick Horgan]

I was building a test program that I wrote a long time ago to check a 
utf-8 code conversion facet, and it will no longer build because the 
line that checks to see if "\xc2\x80" really converts to "\u0080" 
doesn't compile.  This is entirely correct, of course since the current 
draft standard in section 2.3.2 says that any program with universal 
character names in the control character ranges of 0x00–0x1F or 
0x7F–0x9F is ill-formed.  That means I can't say "\u0080". Still, the 
characters are valid unicode, and it makes it more annoying.

Is "\x0\x80" the equivalent, or can there be endianess issues with wide 
chars?
