New Comment:
I guessed as much. Personally I blame stupid text editors for inserting
the character on the ends of lines (which is where I've found them).

Can't do that as people using UTF8 in their scrips might use this
character as part of an identifier.

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
