Hi, this issue has been fixed already in emacs-27, under
bug#37530. You can try out emacs-27, or if you want to stick to
emacs-26 you can apply the patch from the bugfix to your local emacs.

Here it is:

Subject: 26.3;
 Wrong symbol inserted from keyboard: left tack instead of turnstile.
Date: Thu, 26 Mar 2020 12:29:39 +0300

When I type `⊢` (Unicode right tack, also called «turnstile»), the left
tack symbol appears instead. I can insert the turnstile with other
methods without problem.

Note that I have a key bound on my keyboard layout directly to this
symbol. It works across my system, with the sole exception of Emacs.

I suppose the volunteer will have to put the turnstile symbol onto their
keyboard layout. Try to insert turnstile directly from keyboard layout.
* Expected behaviour: a turnstile appears.
* Observed behaviour: left tack appears.
