Yeah, spritefonts aren't great for some languages, and that makes it tricky... unfortunately there's no good way C2 could show you a preview of where the text is going to go - since it depends on hidden details of the browser/OS combination, there's not a good way to know until you run it. Cross-browser testing is always important and you should be doing that anyway, and this is another reason why it's important. As we've always said, the only good workaround is to make sure there is enough free space around text objects to ensure they can fit regardless of any small changes to size/alignment.
