On Google Fonts there is the choice of Latin and Latin extended. What are the differences? On Wikipedia there is Latin Extended A and b. What are these? Are they anything to do with Google Font’s Latin Extended?
By the way, is there a complete list of latin characters anywhere?
I looked at a few languages (French, German, Swedish, Dutch) and it seems they only have a few characters extra on top of the standard A–Z. For example, Swedish only has three extra characters:
Unless you’re using a non-Latin based language (e.g. for Russian you would use Cryllic), isn’t the requirement for diacritics quite limited? When would you ever need or use all these extended Latin characters?
