Running a simple example shows:

What is your locale set to? Is it something non-utf8? Try setting to something like en_US.UTF-8 not en_US. Don’t forget to run locale-gen

See this link on how to change locale in Ubuntu: Locale - Community Help Wiki

Now, window renders without close, maximize and minimize icon. As soon as cursor move on window, it’s
getting changed and there is an error message:

Wayland: Standard cursor shape unavailable

I’m not sure, but that’s maybe because you’re using old glfw version?
I think this pull request fixes by adding decorations: Implement window decorations by linkmauve · Pull Request #1161 · glfw/glfw · GitHub

But you should be able to use glfw with X11 under wayland. That should give you normal looking window. If I’m not mistaken, then installing libglfw3 instead of libglfw3-wayland will choose x11 over wayland under ubunut.
No need to use wayland unless you have very specific reason to use it. XWayland will run your X11 windows under wayland.
