Automated excerpt

So, Base91 worked fine for encrypted file and directory names. On random input, that’s about 31.95 bits per group, or 6.39 bits per character. Unix-only names Unix filenames can contain most of the punctuation Windows rejects. Standard Base91 still contains /, and both alphabets contain characters Windows rejects. Reserved names and case Windows reserves device names such as CON, NUL and COM1, regardless of case.
