Total tangent, but extremely interested in the use of the Yen/Yuan sign as a footnote marker. Is there some history here I’ve overlooked or is this just arbitrary?
Is that a common usage /auf Deutsch/? Such use is listed on the Wikipedia page, but it's a use I don't ever recall having seen before.
Especially on sites like this one, which have no previews.
§ is a bit less common but iirc used in some legal texts. It's also easy to use on ANSI German keyboards with shift+3.
