W3C validator service bug.

Hi
I am using your service API (http://validator.w3.org/docs/api.html) With Parameters:

*         debug = 1

*         output = soap12

*         fragment= <my web page content>

Meaning that character encoding should be detected automatically.
But on any web page content I send to analysis, it always "parses\assumes UTF-8 Encoding" Regardless the page declared encoding.

Needless to say I have tested it on multiple web pages with different encodings - all resulted with UTF-8 Parsing.
Note that in case I'm "Copy\Paste" the content to the W3C validator Web Site (Direct Input) it works correctly and detects the correct encoding.

I saw that you already fixed this bug on the direct input mode - but probably not implemented this fix on the API flow - Bug: https://www.w3.org/Bugs/Public/show_bug.cgi?id=2690
Thanks,
Al.
