Wait, I think I misunderstood. You want chr() to cast to unsigned char? There might be a case for
that. Oops.

Making ord() produce a signed char would make it inconsistent across platforms, as whether char is
signed or not varies. Plus, people are pretty used to it being unsigned.

Description:
------------
http://cvs.php.net/viewvc.cgi/php-src/ext/standard/string.c?revision=1.445.2.14.2.28&view=markup&sortby=date
PHP_FUNCTION(ord) ...
RETURN_LONG((unsigned char) Z_STRVAL_PP(str)[0]);
..
PHP_FUNCTION(chr) ...
temp[0] = (char) Z_LVAL_PP(num);
would not like use (unsigned char) in PHP_FUNCTION(chr) ? or opposite ?
