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):

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.
