w3 error validación UTF8 "\xC3" does not map to Unicode

[jimmy1971]

Sorry, I am unable to validate this document because on line 1006 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 "\xC3" does not map to Unicode

Ese error me tira, peor no logro detectarlo... alguien puede saber que ocurre?
