Błąd walidacji

Witam

Ten szablon nie przechodzi mi walidacji dlaczego? Wyskakuje komunikat:

Sorry, I am unable to validate this document because on line 226 it contained one or more bytes that I cannot interpret as utf-8 (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication. 

The error was: utf8 "\xB3" does not map to Unicode
