Okay. I'll work from that then.

I was hoping to look at that this week, if time allows.

That rings a bell. I will grep my archives...
Relevant messages that I found in my outbox:
<y8e12cb6.fsf at jonadab.homeip.net>, in which, in response to an issue
that Nicu raised, I explained the completely naive approach I had
been taking to character set issues up to that point, and inquired
whether encoding all non-ASCII characters as entities was a viable
solution to the charset issues.
<wttj18io.fsf at jonadab.homeip.net>, in which, after Stephen responds
that he doesn't think named entities will work in XML like they do
in HTML, but he suggests numeric entities, I offer to test numeric
entities to see if Inkscape can handle them okay. I don't recall
whether I ever actually did this testing.
Hmmm... was it maybe in that patch I sent you way back when? Let me
see if I can find that... Hmmm... It doesn't seem to be there.
Well, I can't find the specific message at the moment, but no matter.
I'm pretty sure the problem we intended to solve with this was the
character set issue, and it fundamentally isn't solving that.
Note, however, that unless I'm missing something, we still do need to
encode angle brackets, ampersands, and quote marks. This can be done
by passing encode_entities a second argument that is a string
consisting of the characters that should be encoded, i.e., q('"<>&)

I think it did. But upon closer inspect I think that problem really
needs to be solved in the calling code, or perhaps even in other code
that it calls. I'm now thinking perhaps getforminput() is really the
right place to solve this.

I don't think images that are already in and correct will have
problems with this. It's the images that are failing that are causing
all the problems.
The best solution in technical terms would be to make the whole world
switch to English and do away with non-ASCII characters altogether,
but I think for political reasons we will have to go with some other
solution, even if it's a suboptimal workaround ;-)
In all seriousness, what I really need to do is hunt down a module
that converts charsets to UTF8. Umm... lesse... Unicode::MapUTF8
seems to have something to do with that. I'm putting its
documentation on my reading list.
