I upload my css file and there is no errors, I put the css validator xhtml code on the homepage of my website and I get the following errors:
 
35 Unknown error org.w3c.css.parser.analyzer.TokenMgrError: Lexical error at line 1, column 1. Encountered: "\u6f63" (28515), after : ""
43 Unknown error org.w3c.css.parser.analyzer.TokenMgrError: Lexical error at line 1, column 1. Encountered: "\u616d" (24941), after : ""

Unknown error org.w3c.css.parser.analyzer.TokenMgrError: Lexical error at line 1, column 1. Encountered: "\u6f62" (28514), after : ""
 
etc... (there are 32 total errors all with the same basic info)
 
What exactly is this?
I have never encountered it until recently.  The code on my site is the same as when it initially passed and I tested the link at the time I put the validation code on my site.
