Do you read the characters from the keyboard?
And had you pressed RETURN in the above example?

If so, in order to be prepared for a variety of keyboards and
systems and character handling done by systems or run time
libraries, you can hide the details of what character you
will get for RETURN.
If you know that you will either get Latin_1.CR or Latin_1.LF,
and both Characters have the same meaning in your application, they
both could be mapped to the same character by a wrapper function,
for example.
