There is a similar bug on file (https://bugs.chromium.org/p/chromium/issues/detail?id=274041). This solution is a much narrower scope, allowing the user to set the device name only when they format the device. While not ideal, the approach provides the desired feature but bypasses many of the technical hurdles mentioned in the other bug: 

Most importantly, formatting already requires unmounting the device and invalidating all references to the files it contained. 

Since the OS does not give the user a choice of file systems to use, the issue of supporting multiple file systems is also moot.

Regarding character sets, I suggest initially only allowing characters that are generally supported. As a second step you can add a checkbox that defaults to "Require Broadly Supported Names", with a help blurb explaining that unchecking the box will allow you to use characters that may cause errors on some devices.
