When adding or modifying external URLs, ensure international/non-ASCII URLs are **percent-encoded** (UTF-8 → percent-encoding). Do not treat “escape” as a vague idea—use proper URL encoding so links render correctly across clients and avoid malformed/ambiguous URL behavior. Apply this during link updates: - Percent-encode international characters in the URL path/query (e.g., Tamil, accented characters). - Ensure the final URL string is valid and copy-pastable. Example (conceptual): ```text Incorrect (not encoded): http://example.com/புத்தகம்?q=தேர்வு Correct (encoded): http://example.com/%E0%AE/....?q=%E0%AE/.... ``` If you’re unsure, re-encode the URL using your language/runtime’s URL/URI utilities before committing documentation or code changes.
