Weirdest Bug when copying from a pdf

When copying to sets from a pdf I get a wild bug where the text gets converted to what google translate thinks is Korean. Input text: S = {(a, b), (b, c), (c, d), (d, a), (a, d)}
R = {(b, c), (c, a), (a, b), (d, c), (c, d)} Output text: 푆 = {(푎, 푏), (푏, 푐), (푐, 푑), (푑, 푎), (푎, 푑)} 푅 = {(푏, 푐), (푐, 푎), (푎, 푏), (푑, 푐), (푐, 푑)}
OS version: NixOS 24.11.20240921.9357f4f
App version: 8.1.1.27
Downloaded from: Nixos unstable.
Additional information: I use cliphist for copy and paste on hyprland. Also copying the text from both okular and libreoffice works as expected. I would attach the sample file, but because this is my first post I can’t.

Hello @Dr.Void, please provide the following:
