My suggestion finds high-bit characters (127-255), but you need to find
printable characters with the exception of \n and \r. So my suggestion
won't work for you, I'm afraid. Perhaps you want something like below?

$bad_string_flag = ! ctype_print(strtr($string, "\n\r", "  "));

>From the docs, it seems that replacement string in strtr cannot be null for
correct operation, so I've used double blanks (or use any chars,
e.g. "NR"). The strtr part feels a bit clumsy, but you might be able to
find a better way in "XVII. Character Type Functions" or "CLXI. String
Functions" (PHP Manual).

Abdullah
