I'd expect if you have a charset
declaration in your file (such as <meta http-equiv="Content-type" content="text/html;charset=UTF-8">
in your head
section) that the webcrawler would understand the unicode characters for those letters. But really you'd have to test these out and/or ask Google.
I wonder if your inference that Google's webcrawler isn't processing the entities correctly (on the basis of what you're seeing in the webmaster tools) is actually correct; I'm not saying it isn't, but it's an assumption I'd test. I'd be a bit surprised, really, if Google's webcrawler didn't understand the entities (Å
for Å
, etc.), most browsers do, even in the title.
But using a proper charset is probably your best bet. Make sure the charset you declare is the one your editor and other tools are actually producing!
