URLConnection.guessContentTypeFromStream() does not support UTF8 and UTF32 with BOM

[Chris Hegarty]

I think Alan mentioned it in an earlier mail, this is a legacy API and 
not widely used. I can't say I've come across its use more than a 
handful of times in more than 10 years.

If you have a small patch that resolves a particular issue then maybe we 
should just proceed with getting it in.
