The names of uploaded files are normalised to NFC. This means that if you upload two files that have names that are different on the filesystem, it's possible that the server will, even if it faithfully round-trips the filenames, return them with the same filename.

Quoting NARUSE, Yui from W3C bug number 14526 comment number 18 (https://www.w3.org/Bugs/Public/show_bug.cgi?id=14526#c18):
>
> Imagine following situation, a directory has two file, U+795E.txt and
> U+FA19.txt.
> And the user want to upload them. As you can notice, DOM and uploaded server
> can't distinguish them. Normalization considered harmful.
> [...]
> Yes, current WebKit normalizes those Kanjis, and it is considered breakage.
> You can see the breakage by uploading U+FA19.txt.
> After uploading, it become U+795E.txt and you can find the left part of the
> Kanji is changed.
> These kanjis have the same meaning "god", and specified as compatibility
> character thorough some political reason, but people don't want to
> normalize them other than the true normalization situation.
