[CSS21] Question on character escapes

I'm wondering what happens when \nnnnnnn escapes (backslash followed by numbers) 
are used and the resulting character is invalid (eg it's a high or low 
surrogate, or is above 0x00110000).  Should the escape be treated as U+FFFD?  Or 
should this be considered an error and error recovery (skipping a declaration or 
whatever needs to happen at that point in parsing) happen?  Or something else?
