Certain unicode chars / combos crash client

My game has randomly crashed as I've listed more items for sale, I thought it was due to getting in red maps with cyclone + pops.

However, it was very intermittent, and often in bursts.

Then today, I tried to use the trade site to message someone to buy something, and it kept crashing on DM send.

I tried pasting in chat to manually dm, still fails.

Then, I tried pasting char by char, and found the one that crashes it.

The partial name is "fÍxÍtิ"

If I paste in the "Í", no problem.

But, the second I paste the "tิ", game crash.

And presumably when someone with a bad char messages me, also crash (unconfirmed).
