llms.txt and robots.txt were served without a charset, so browsers decoded the valid UTF-8 as Windows-1252 and showed mojibake (â€", für). - Add `charset utf-8;` (+ charset_types) so text responses carry `; charset=utf-8`. - Add an explicit `location ~* \.txt$` that serves the file as plain text, returns 404 instead of falling back to the SPA index.html, and sets `Access-Control-Allow-Origin: *` so any AI crawler/tool can fetch llms.txt / llms-full.txt cross-origin.
