That issue can be reproduced in cmd but **not** in mintty. Here is a screenshot in mintty. 

I have used qrencode in bare metal Linux installation and it works perfect in both ansi256 and utf8 mode. The issue is in the Windows conhost. I slightly remember some...

In my setup, those are already in that path.

Is it not required to copy certificates manually. Try to update the packages with `pacman -Syyu` twice or use new installer from the website.

Technically speaking, there is something common between git-for-windows and msys2.

@gabyx Can you provide equivalent code in C?

Can you provide the command you want to run and the output of it?

One shared library got extra `lib` prefix in its name.

The main hurdle is that CI can not compile the qt static package due to the size of it. One package maintainer has to dedicate an entire day for it.

For general CI guidelines, this can be followed https://www.msys2.org/docs/ci/. Some projects use msys2/mingw in CI. e.g. [gstreamer](https://gitlab.freedesktop.org/gstreamer/gst-ci), [pango](https://gitlab.gnome.org/GNOME/pango), [fontconfig](https://gitlab.freedesktop.org/fontconfig/fontconfig), [inkscape](https://gitlab.com/inkscape/inkscape) etc.
