Hello Jonathan, Thank you for your response.
mailto: links are indeed standard, with Mozilla products (since Netscape 4.x) supporting only part of the standard. Since the format of the URL is "application/x-www-form-urlencoded", both + and %20 should be supported -- see RFC 2368 <https://tools.ietf.org/html/rfc2368>, RFC 1738 <https://tools.ietf.org/html/rfc1738> and RFC 3986 <https://tools.ietf.org/html/rfc3986>.
