Unfortunately, there didn't seem to be any thing like charset or anything information about the encoding in the HTML. However, luckily (since I am a bit of an encoding wimp), it turned out that I just had to choose 'UTF8' instead of the default 'Windows ANSI' as 'file origin' when importing into Excel and everything was fine. Doh!
