getRandomChar

protected char getRandomChar(java.util.Random random)

Return the next random character from the sequence generator. What we want is to get an ascii value between 33 (exclamation point, 32 is a space char which is not useful) and 126 (tilde, 127 is the DEL character which is not useful). This inclusive range encompasses all the upper and lower case letters, numbers, and punctuation characters. If the resulting character is in badChars, then we repeat the process to get something acceptable.
