Today I tried to upgrade one of my applications from 5.4.3 to 5.4.4 on Android and failed (Android Studio 3.2, 3.4 and 3.5 on Windows 10). A jassert is hit in juce_String.cpp that String is created from char with codes above 127 etc. (probably when JNIBaseClass is called). An empty demo project generated by Projucer (GUI App) does not work too.
5.4.3 version works as expected.
Edit: so it seems that the problem is on Windows only. Everything works ok on Linux and MacOS (AS 3.5 + JUCE 5.4.4).
