If the idea is to spot malicious filenames that have confusable
characters then I think the problem is much larger than just confusing
space characters. For example “.аl‌ias”, with a letter from the Cyrillic
alphabet and a zero-width space. I think that particular problem is out
of scope for the nobreak-char-display feature.
