Document cannot be checked because of invalid character

Sometimes there is included a non utf-8 character , or some other type 
that the validator cannot read.
It gives the line number, but will not show the source.

Since my code usually contains a number of php "includes",  the line 
number is not helpful in finding the invalid character,  in which case, 
I wish the validator also showed the source code.

thanks.
