This got rid of my "qt.qpa.fonts: Unable to open default EUDC font" error



  • Re: qt.qpa.fonts: Unable to open default EUDC font: "C:\WINDOWS\FONTS\EUDC.TTE"

    I just ran into this problem last night after installing PyQt5 for Windows 10 Pro 20H2 and Python 3.9.4 64-bit. I have no idea what a EUDC.TTE file is (couldn't find one on my system that has been updated since initial Windows 7 pro install). Anyway, I did a registry search for EUDC and changed the entries from EUDC.TTE to ASIMOV.TTF. That got rid of the "qt.qpa.fonts: Unable to open default EUDC font: C:\WINDOWS\FONTS\EUDC.TTE" message inside my Visual Studio Code terminal.

    I chose ASIMOV.TTF because it's a font that would stand out if it gets used. I haven't seen the font appear anywhere in my Python app or in Qt Designer while finishing up my project.
