Look it up.

Some things you don't memorize — you look them up, ideally in a page you trust and can copy from cleanly. That's what this section collects: developer tables (HTTP status codes, ASCII, regex, keyboard glyphs), the special characters and emoji that aren't on your keyboard, and the quick kitchen conversions you end up searching mid-recipe. Everything is searchable, everything is tap-to-copy where it makes sense, and it all runs in your browser. These are the pages worth bookmarking now, so the answer is waiting the next time you need it rather than buried three results deep in a search you'll only end up running again next month.
