The challenge

The shortest code by character count, that will input a string using only alphabetical characters (upper and lower case), numbers, commas, periods and question mark, and returns a representation of the string in Morse code. The Morse code output should consist of a dash (-, ascii 0x2D) for a long beep (aka 'dah') and a dot (., ascii 0x2E) for short beep (aka 'dit').

Each letter should be separated by a space (' ', ascii 0x20), and each word should be separated by a forward slash (/, ascii 0x2F).

Test cases:

Input:
    Hello world

Output:
    .... . .-.. .-.. --- / .-- --- .-. .-.. -..

Input:
    Hello, Stackoverflow.

Output:
    .... . .-.. .-.. --- --..-- / ... - .- -.-. -.- --- ...- . .-. ..-. .-.. --- .-- .-.-.-

Code count includes input/output (i.e full program).
