If I'm allowed to add some further examples (which are probably known to most, but maybe not to all), registry value names allow *any* Unicode character (including NUL, sic! - thanks UNICODE_STRING), so the following is completely ambiguous, even though valid: /proc/registry/.../parentkey/subkey/value/with/slashes where the actual value name is "value/with/slashes" (sic!). That's from Win32 (and POSIX) file system functions taking one argument for the file name, and the Win32 registry functions taking two distinct arguments to form a full path (and non-ASCIIZ length-prefixed UNICODE_STRING).
