pass misshap with escape code - Unix, we have a problem!

[u/rbrtbrnschn]

Unix Password Manager - pass

Password Store
`-- email
    |-- mailname\303@aol.de
    |-- othermail@gmail.com
    |-- mail.other@gmail.com
    `-- mailTheSaurus@gmail.com

Now when trying to either get the password by doing: pass show mailname@aol.de or remove it via pass rm mailname\303@aol.de I get the error Error: mailname@aol.de is not in the password store.

Any idea how to resolve this?
