YES!! Then I know what's wrong! Will fix it with the next update thanks!!
I uploaded a new experimental build here! https://zittacheng.itch.io/uploadtext (password: REDACTED)
That build (both web and PC version) should theoretically fix the problem, but I can't be sure because I can't find a PC with the correct culture setting to test it...If you have the time, can you check real quick whether the build works for you? You've been a great help, thanks for still sticking with this game!
