Bug special characters

Some bugs regarding characters are noted in the web interface.

  1. Response with special characters are not accepted.

Example:

.
[ ]
{ }
*
I develop a Linux course and each character has a meaning.

  1. I also noticed that there is no difference between uppercase and lowercase letters. another problem. For in the course the command “ls -laF” is different from the “LS -laf” command.
