Bug description: Nonbreaking whitespace breaks parsing
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
