Research font accents within Olivero's typography

• I did some quick research on special characters that appear in German, and it looks like it might just be Ää Öö Üü ẞß. I grabbed that research from this wikipedia page. I'm not sure if there's any more that we're missing? @mherchel volunteered to reach out to the German community to ask.
• I looked at the Lora glyphs page and it looks like they don't have them all listed.
• I tested out these special glyphs using the actual Metropolis font and Lora font in Figma, and it looks like they appear correctly (see attached screenshot). So maybe the documentation is incorrect? Again, there could be some glyphs that I'm completely missing that are indeed German, but with the German lorem ipsum text that I also included in the screenshot, it all tests out ok. Nothing is missing or rendering incorrectly
• Next steps: 1. reach out to the German community to see if there are glyphs that we are not accounting for. 2. Do we also want to just put a general call out to the international community to test out the theme with their language to see if everything is rendering correctly?

I am German and offered help. mherchel gave me login credentials and I added this content: https://tugboat-bf5udo5tbzfdng7rycgs71zt6kcb2fhl.tugboat.qa/node/60

As far as I know, the Umlauts tested by jwitkowski79 are all that we have. The capital ß is fairly new and most Germans don't really know about it. It can't even be written on a Mac and that one is the only one that doesn't seem to be covered by the font. Since this letter never stands at the beginning of a word, it only applies when writing all uppercase words. On websites, imho this is usually done with a css declaration, which would turn the ß into SS.

I can't think of any other special characters for German, I did some research but couldn't come up with anything.
