Well ... assuming zsh implements equivalence based on character 
normalization. And you have two files with names: <00E4> ("standard" 
single character ä) and <0061><0308> (a with combining diaeresis). Now 
completion listing will present to you

ä ä

Which one are you going to select?

It is different from case insensitive file systems where you never can 
get both forms at once (FOO and foo).
