Hi,
I used your css validator and my css were fine. one day, I decide to verify to make sure it's still okay and I found out they aren't. I got that error which I don't understand and it's not in the FAQ.
Target: http://www.progmatik.com/en/
I/O Error: Invalid byte 2 of 3-byte UTF-8 sequence.
Thanks for helping me validate my css :)
Best Regards,
Mart
