Nice idea!
I think writing these characters with the 8th bit set, is a kind of dangerous. E.g some ftp-clients or text editors can do really strange things with these accented characters.
When I write such kind of programms I will use hex in my hashes. Instead of "ä" I would use "\xe4" and put "äá" etc. in a comment on the same line
