There is one big difference: CLI utilities don't usually care about diacritics (though encoding issues can throw a wrench in that), but they care a lot about spaces. So putting spaces in filenames requires properly quoting or escaping parameters, whereas diacritics does not. That makes one-off shell snippets and scripts a lot more annoying (though TBH I tend to shy away from those anyway, these days).
