While this (probably) still applies to Apple UI elements when they switched to APFS they stopped doing Unicode normalization on filesystem level. So now on macOS you can have a very mixed bag with some programs normalizing, some not (it's a bug) and many expecting normalized file names. So it's kinda like other Linux now except a lot of dev assuming normalization is happening (and in some cases still is when the string passes through certain APIs). Worse due to normalization now being somewhat application/framework dependent and often going beyond basic Unicode normalization it can lead to quite not so funny bugs. But luckily most users will never run into any of this bugs even if the use characters which might need normalization.
