If a string is short, it will probably reside in the processor cache, so there is no real memory i/o overhead here. For more longer strings, it may be better to do that in short chunks, so each chunk can reside in the cache. But I don't think filenames are long, so it is not an issue here.

I think the second part can be rather generic to be reused for hashing something else that does not require filename specific case-folding.
