Exactly. To make things worse, space is a protocol element in link lines
and *can't* be left unencoded by the author, whichever way we choose.

I agree. But what we can have (and it's messy, but not as messy as the
alternatives) is "authors encode percent and space" and "clients encode all
other reserved and non-ASCII characters."

That's the best you can do. But in the case where the link line is

then the client must translate it for sending over the wire into
gemini://
teddybearoftheyear.com/vote?%D0%98%D0%B2%D0%B0%D0%BD%20%D0%93%D1%80%D0%BE%D
0%B7%D0%BD%D1%8B%D0%B9
<http://teddybearoftheyear.com/vote?ew0k%20The%20Great>
because making the author type all that is wholly abominable. Online
URL-encoders are not that helpful, because they give you + instead of %20.
[1] This is Ivan the Terrible, who for most of his life was actually a
quite effective tsar despite his (occupational) paranoia and a serious
outbreak of madness just before he died; a better translation would be
"Ivan the Formidable". Still, nobody would call him a teddy bear (and so
his ukase "Vote for me!" would probably be in vain).
[2] The latest spec change makes this line incorrect unless "
teddybearoftheyear.com/vote" is to be interpreted as a relative path. It
needs to be prefixed by "gemini://" or at the very least "//".
[3] If the space had not been %-encoded by the author, the Tsar's second
name would be part of the link name and not part of the IRI.
