It looks like that file might really be invalid. I tossed it at a few xml validators and they were unhappy, a few others thought it was fine. You'd probably want to run this by someone with more unicode experience just in case.

The line it's choking on is:
> <ኢትዮጵያ>አዲስ አበባ</ኢትዮጵያ>

Which I think in python dumps out to be:
> <\u12a2\u1275\u12ee\u1335\u12eb>\u12a0\u12f2\u1235 \u12a0\u1260\u1263</\u12a2\u1275\u12ee\u1335\u12eb>

In theory we could be messing up the conversion on our side when we go from UTF-8 -> UTF-16

Not sure if this helps, but if you see the attachments you'd notice that other browsers don't seem to be having a problem with it. So wouldn't this bug be browser specific? 

I'm no expert, but are the validators that different between these browsers?

XML 1.0 had a strong name character restriction until 5th edition [1]. ኢ (U+12A2) had not been included in the allowed character list. XML 5th loosened up the restriction so that basically almost all characters (except PUAs and unpaired surrogates) are allowed [2].

Our XML parser is fairly old and it does not catch up XML 5th Ed.

I found an existing bug.
