Fix output format borken in char --list (#13417)
# Description

Resolve #13395 

When we use the `char --list` command, it also outputs the characters
*bel* and *backspace*, which breaks the table's alignment.

I also found that the behaviour at the beginning of the table is not
correct because of some line change characters, as I mentioned in the
issue discussion.

So, the solution is to create a list containing the characters that do
not need to be output. When the name is in the list, we output the
character as an empty string. Here is the behaviour after fixing.
