Why do URLs need to be encoded?

URLs can only use ASCII. Encoding replaces unsafe characters with a "%" followed by two hex digits.

Is it safe for URLs with auth tokens?

Yes. Encoding and decoding happen in your browser; nothing is sent to our servers.

Does it encode every character?

It encodes special characters and spaces; standard letters and numbers stay as-is per URL encoding rules.
