Comparison of the English and German language wiki page for math symbols.

and

https://de.wikipedia.org/w/index.php?title=Liste_mathematischer_Symbole&oldid=266615032

To be fair, if you go to the linked “List of logic symbols” article that has a table with Latex, Unicode, and even HTML codes. But it’s only for logic symbols, no page for all mathematic symbols on the English Wikipedia as far as I can see, so no quick Ctrl+F searching for unicode/latex. :( And most other subsections don’t even have a link to such a list.
