These bytes represent the word "hi" in UTF-32LE:
FF FE 00 00 68 00 00 00 69 00 00 00
However this is what Notepad displays:
回答1:
Notepad does not support UTF-32, only ANSI, UTF-8, and UTF-16. It is interpreting the first 2 bytes as a UTF-16LE BOM, not the first 4 bytes as a UTF-32LE BOM, so the file bytes get interpreted as
FF FE 00 00 68 00 00 00 69 00 00 00
Instead of
FF FE 00 00 68 00 00 00 69 00 00 00
