Indeed, GLUT is not in active development (I would not say that it is "effectively dead" but rather that it "crystallized into a perfect form", but I digress). However, I was asking about "freeglut", which is a different thing, which is actively developed: last commit on 2019-03-26 dropped some unnecessary dependencies, for example.

I remember GLUT having some pretty significant deficiencies last time I looked at it. I guess FreeGLUT has added support for stuff like Unicode, high-DPI displays, etc... in the intervening years?

I just use freeglut to open a window and throw opengl into it, in a more or less portable way. The "gui" and "font" parts of freeglut are not really very useful (and they are missing in glfw anyway). Thus, unicode and high-dpi issues should be of no concern: as long as you can draw to your window and receive user input, what else do you need? What do you mean exactly by high-dpi "support"?

You have to explicitly opt into a Retina display context on MacOS in order to get a window into which you can render at high DPI (2x the physical dimensions). You cannot mimic this with transform matrices; the render target will be rasterized at low-DPI and interpolated.

So, yes, high-DPI issues very much exist, and GLFW does the right thing.
