First Character In Update Returning with Unicode = 65279

I have an integration calling an Integormat webhook when an update is posted.

The scenario suddenly stopped working. After further investigation, I found that a unicode character (65279) was being added to the beginning of the textBody. After further, further investigation, I found the same thing when I copied the text directly when I edit the update after posting it.

What the heck?!

Does anyone have any idea what’s going on?
