Comparison of the English and German language wiki page for math symbols.
https://en.wikipedia.org/w/index.php?title=Glossary_of_mathematical_symbols&oldid=1342073856
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.
To be fair the article is called a glossary, so I guess it’s understandable. But if you click the switch language button it brings you to the German one with the table. Guess if we want a real equivalent in English somebody needs to create a new article for that.
