They're exposed to the programmer and the program's users.  Either may
want them on command-line arguments, in config files, etc.  It will be
inconvenient if LMDB requires different string handling for non-ASCII
filenames and non-ASCII DB names in such cases.  The programmer may
choose to use different string handling but let's try to avoid forcing
him to do so.
