I made reply to the bug #2069 before seeing this post

In my enviroment, it works as expected.
Perhaps it is environmetal dependent.

At 5.2.4 build, I used dependency libraries distribiuted by Msys2.
At that time version of libfonfconfig is 2.13.1.


I have updated libraries on Msys2 system.
Now Version of fontconfig is 2.13.1.

I will re-packge windows binaries for 5.2.4 on this weekend.
