If the data has a BOM it's UTF-16, if it doesn't, but is known to be little
endian it's UTF-16LE.
Seeing two boxes is not conclusive. If the file system happily stores these
at the original code points, then *it* would support UTF-16, even if the
shell, or the text output API underneath it, that was used to display the
name does not.
Only by looking at the string with a debugger would you know for sure that
VFAT indeed kept the string and didn't mangle the string.
One other possible test would be to try to present the file system with a
string that's longer than the maximum number of characters, where the last
character is an unpaired surrogate - it would be interesting to see what it
