It's the special unicode character u+202E (RLO) (=Right-To-Left Override)
It reverses any text following it, and it spills over other html tags too, it's an huge mess. If you use that special character into the "Subject" field, it's going to reverse the whole post header. (it has no effect inside the email field)
This site board doesn't properly escape that character, as it should instead for all special characters.

Generating that character by pure windows seems like an hassle, it's a bit more easy with notepad++

notepad++ --> run --> charmap --> find the character U+202E --> copy --> paste inside np++
I got my copy of that character by just copying raw html text from inspecting a post from /AM/ where this character was first used, and then pasting that text into notepad++, which allowed me to see all the special characters normally hidden, including that [RLO] char.

I'm placing the RLO under this row, between the arrows --->‮>>/operate/19673@19673
Have fun with it until this is fixed.
