Description:
------------
If a line contains a non-breaking white space (\xA0) trim doesnt strip it, it should as its a "space" character

This can easily be bypassed by sending the \xA0 character in the option parameter but it took a while to figure out there was a non-breaking space character in the string

Test script:
---------------
<?php

$string = " \xA0";
echo strlen(trim($string));

Expected result:
----------------
the script should output a length of 0

Actual result:
--------------
The script outputs a length of 1 as trim doesnt strip the non breaking space

There are multibyte encodings which are ASCII compatible where a0 is a valid byte 
in non-space characters, Shift JIS being the most obvious one. There would also 
be the issue that a0 is only part of the non-breaking space character in UTF-8 — 
to trim UTF-8 NBSPs, you'd have to also include c2, which would cause even more 
problems.

As a result, we can't really change this. Closing won't fix.
