Navigating files named with alt codes

  alt, cmd, filenames, windows

So, being the classic minimalist with my desktop preferences, I would like to have un-named folders/directories that use icons to show me what is in them rather than, well…. names.
e.g an old floppy disk icon for my programming workspaces and a camera for photography. All the classics.

But, if I have any files stored there and try to run things or open them from programs such as Visual Studio, Adobe Photoshop or even from cmd the computer cannot find the path. Now obviously the issue is that it doesn’t like the alt255 code I am using(wondering why this is the case).

I would really like to know if there is a way to have un-named folders/directories and still be able to actually use them properly. Preferrably without third party software although if you are aware of any do let me know.
