It works for English, but sadly the selected fonts don't always have all the national characters. Sometimes there are similar enough replacements (e.g. Charis instead of Charter) but not always.
I agree, since I build multi-lingual web sites. I hope this will be helpful.
There is a little box at the top that allows you to replace the default text with the text of your choice to test whether your specific non-ASCII characters will work.
