I just tested 1.8 beta and the font manager is a superb addition. However, I don’t see an option to select a character set for Google Fonts. I assumed it would download the Latin Basic set by default. But strangely, some languages from the Latin Extended set are displayed correctly, even though font filenames do not suggest it.
However, we would also need the option to select Greek, Cyrillic, Vietnamese character sets, if the font supports it. I don’t understand how characters from Latin Extended (Central European languages) worked in my case, but it would probably be better to explicitly download the Latin Extended set.
On some sites users might want to add names (for example: places or people) in the local spelling, and then additional scripts, like Greek or Cyrillic would be required.
Greetings,
