Git::GitPath.new(‘302265’).unescape # => “µ”
@example
larger than 0x80 (e.g. octal 302265 for “micro” in UTF-8).
characters (e.g. t for TAB, n for LF, \ for backslash) or bytes with values
characters in the path with backslashes in the same way C escapes control
Git commands that output paths (e.g. ls-files, diff), will escape unusual
