When establishing a connection to an SSH server, WebSSH tries to guess at its encoding using a command sent prior to opening the terminal. Unfortunately, sometimes this can return data which does not form proper input for the `encode` function used by `is_valid_encoding` to test whether the encoding is known. In particular, we ran in to a case where the server was returning a string which had a \0 in it when converted to ascii. That raised a `ValueError` (as opposed to `LookupError`), which was uncaught. Handle the `ValueError` case as well, treating it as an unknown encoding so that we fall back on the default.
