strlen stops at the first NUL byte which breaks getting a proper grid when the message contains any of them. The message length is known at this point and can be passed to iec16022init instead of the message pointer.
It seems odd to believe the underlying library has a bug requires us to always append a blank at the end of the input. There might be some edge cases where this is necessary but I did not encounter any so far.

Edit: I now also removed the workaround that appended a blank to every input string. The
strcatmethod also can't handle NUL bytes and I couldn't find a use case where this sort of fiddling was necessary in the first place.
