stripLow function

String stripLow (
  1. String str,
  2. [bool keep_new_lines]
)

remove characters with a numerical value < 32 and 127.

If keep_new_lines is true, newline characters are preserved (\n and \r, hex 0xA and 0xD).

Implementation

String stripLow(String str, [bool keep_new_lines]) {
  String chars = keep_new_lines == true ? '\x00-\x09\x0B\x0C\x0E-\x1F\x7F' : '\x00-\x1F\x7F';
  return blacklist(str, chars);
}
