Sure, I'll forward this question on. I'll see if I can get someone from
their team who could be available to answer questions such as these in
the future - Microsoft is interested in maintaining compatiblity between
Linux and Windows exFAT implementations.
Hello Sasha! Have you got any answer from exfat MS team about upcase
table for Unicode code points above U+FFFF?
Sorry for taking so long. This is my understanding from the Windows
folks: Windows filesystems just don't support variable encoding length,
and expect UCS-2 strings.
