Hello,
RFC6068 section 5 recommends encoding the space character as %20, where
URI.pm uses '+' which is discouraged (though not forbidden)
quoting RFC6068:
| Current implementations encode
| a space as '+', but this creates problems because such a '+' standing
| for a space cannot be distinguished from a real '+' in a 'mailto'
| URI. When producing 'mailto' URIs, all spaces SHOULD be encoded as
| %20, and '+' characters MAY be encoded as %2B. Please note that '+'
| characters are frequently used as part of an email address to
| indicate a subaddress, as for example in <bill+ietf@example.org>.
Changing the encoding of space to %20 would also fix interoperability
problems with Thunderbird and possibly other MUAs: Thunderbird uses '+'
characters as such and does not back-replace them with spaces.
Ciao,
Alexander Wuerstlein.
