Created Issue: xinclude / encoding problem

hello
i've a problem with encoding and i can't resolve it.
I have a project which use the .net 2 xml api and everything work fine.
but if i have a file which contains strange characters (i don't put an example, otherwise codeplex refuse my post), xinclude don't word (but .net work)

the error message is :
..., valeur hexadécimale 0x0B, est un caractère non valide. Ligne 3, position 31."

i have made an example project which reproduce the bug
do you know how to solve that problem ?
although i admit i'm a bit lost, i think it's a encoding problem

thanks
