Could it be possible that you are returning your string with an extra space at the end?

CHAR_TO_MORSE[x]

How do you call the dictionary in Javascipt?

Javascript: CHAR_TO_MORSE
Ruby: $CHAR_TO_MORSE
Pyhton: CHAR_TO_MORSE

Not sure which language you're using, but for Ruby it looks like the variable is $CHAR_TO_MORSE.

The dictionary is simply an object called CHAR_TO_MORSE that holds values and their equivalents. So call upon it as you would a regular object.

You cannot view the tests without completing for forfiting the kata but what you could do is log the variables to the console window?
