Not really. The purpose of that functionality is for platforms that do not
speak ASCII natively to provide a way to make the protocols we use that are
ascii-based to still work fine.

HTML is contents that libcurl may deliver. How to deal with that data is
beyond what libcurl knows or cares about. You would need to read up on how
HTML works to figure this out. Of course, there may be HTTP headers in some or
many cases that help you out.
