Display not parsing xorg.conf with utf-8 characters

If I install ubuntu using as default the spanish language, xorg.conf will have:

.....

Section "Monitor"
  option "DPMS"
  identifier "Monitor genérico"
......

Section "Screen"
  Identifier "Default Screen"
  Device "NVIDIA Corporation NV15DDR [GeForce2 Ti]"
  Monitor "Monitor genérico"
......

Display is unable to change anything from the xorg.conf, and it will output this (my interpretation is the character í that is causing the problem):
