Note this line in the wiki re chr():
Note: When used with echo() the output to the console for character codes
greater than 127 is platform dependent.
Also code-points above 0x7F are actually stored as 2 bytes
U+0080 U+07FF 2 bytes 110xxxxx 10xxxxxx wikipedia
The UTF-8 ASCII 'compatability' in terms if byte code is only for 00-7F.
@Torsten, according to Wikipedia, 0x00 is NULL and is a valid code point.
