@Ian - as per the function comment, Encode a single character i. I suspect that you are passing something else i.e. a numeric value like
Error using encodeCharacter (line 8)
or any other character. Note that you can only pass in one character. If you pass in 2 or more, then a different assert will fire.

That is what an assert does. If the assertion fails (here that means that in is not a char), then an error is thrown and the message 'Assertion failed.' is thrown.
% Assertion is true -> no error
in = '5';
% Assertion is false -> error
in = 5;
