Thank you, but it's probably better to always return an unencoded string from 
image_find_image_fd in that case. The current code looks like a premature 
optimisation.

Maybe and in practice you are probably right, but the NS port is not exclusive 
to macOS.
There is the quasi-NFD normalisation step but I'm not sure how important that 
is today. There's no need to convert to NFD for accessing files; it only 
matters when comparing names (much like case folding on many file systems).
