HFS+ stores files in decomposed UTF-8. Checking the system headers,

it can store files with a maximum file name length of 255 bytes.
How do you get 256 bytes of UTF-8 into 255 bytes?
Checking the system header hfs_format.h for HFSUniStr255 one sees
that it can store file names with a maximum length of 255 u_int16_t.
And there is no real problem of putting the 128 shorts of Utf-16
into 255 u_int16_t.
It's actually the VFS layer I was thinking of. The OS X VFS uses
UTF-8 (otherwise there would be no backward compatibility for calls
like open(2) etc). I got the 255 byte limit by looking at struct
dirent defined in /usr/include/sys/dirent.h which is the structure
used in the readdir syscall.
