Cannot reproduce Greek characters removed on XF 2.1

[Ivancas]

Affected version

2.1.12

If you enter the following text on XenForo 2.1
𝛿 doesn't render, but ẟ does 𝜃 doesn't render, but θ does

XenForo deletes the first 2 greek characters so the post looks like this:
doesn't render, but ẟ does doesn't render, but θ does

I was able to reproduce this on a clean XF 2.1 setup so it seems a bug. I couldn't reproduce it on XenForo 2.2

I couldn't reproduce it on XenForo 2.2

FWIW I cannot reproduce this on XF 2.1 either.

Even so, please note that XF 2.1 will no longer be receiving any maintenance releases as XF 2.2 is now the primary focus.

If things change and you're able to reproduce this in XF 2.2 then please do let us know, but for now we'll cose this.
