Description:
------------
In most (Windows) fonts, character 0xa0 renders as a blank (nonbreaking) space. Some people use text editors that for whatever reason like to use 0xa0 at random locations instead of ordinary spaces. The result is code that _looks_ correct, but when run can trigger a parse error for no apparent reason.

In zend_language_scanner.l, 0xa0 is recognised as a LABEL character (which means, among other things, that you could have a variable called "$ ");. Assuming no-one is perverted enough to do something like that, it should be safe to reassign it to WHITESPACE (will this cause grief in other character sets?).


Reproduce code:
---------------
<?php
//There is an 0xa0 character immediately following the
// brace on the next line
for($i=0; $i<5; $i++){ 
echo  "Hello, World\n";
}
?>


Expected result:
----------------
Hello, World
Hello, World
Hello, World
Hello, World
Hello, World


Actual result:
--------------
Parse error: parse error, unexpected T_ECHO in C:\test.php on line 5
