allBytesDisplayable

public static boolean allBytesDisplayable(byte[] bytes)

If the value is in the unprintable ASCII range (< 32) and is not a:

• Tab (9)
• Linefeed (10)
• Carriage return (13)

or the byte is Delete (127) then this method will return false. Also, if the byte array has a NULL byte (0) that occurs anywhere besides the last character, return false. We will allow the NULL byte as a special case at the end of the string.
