when I try the w3's validator, I get this helpful little message:
Sorry, I am unable to validate this document because on line 388, 418, 436, 465, 484, 493, 497, 503, 511, 519, 584, 606, 618, 650, 652, 680, 751, 755, 768, 772 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.
Where can I find the source with line numbers? The numbers in my editor don't match up - i.e. line 388 is blank.
