hi!
they aren't three machines but three ways to do "the same
thing" in the same XP box. If everything was working fine,
both the first and the second ways (both using [[cntrl]]),
one PCRE and other POSIX should return the same result,
isn't it?
I've confirmed that Ï = C3 AF (in utf-8) and AF seems to be
a reserved position under win-1252 so, your explanation have
sense, assuming that reserved chars = control chars, but it
should work the same under both PCRE and POSIX replace, or
am I wrong?

such posix caracther classes depend on the current locale.
if you use setlocale() on the 3 machines with the same locale you'll
get the same results. (the definition of a control char is collected
from the iscntrl() system function)

Description:
------------
I was using one simple preg_replace() to clean strings from
control characters and, under XP I found that some utf-8
characters are also modified although they don't contain
control characters (\x-\1f and \7f) at all.
Same code seems to work properly under MacOS X and linux.
Please note that code below is utf-8 and should be pasted with
the editor in that mode. The char failing seems to be the
upper i with dieresis: Ï
The example include the non-working example (first) plus two
alternatives that work properly under XP.
Ciao :-)
Reproduce code:
---------------
<?php
$orig = "IIÏÏïï";
$dest = preg_replace("/[[:cntrl:]]/","",$orig);
echo $dest;
echo "\n<br>\n";
$orig = "IIÏÏïï";
$dest = ereg_replace("[[:cntrl:]]","",$orig);
echo $dest;
echo "\n<br>\n";
$orig = "IIÏÏïï";
$dest = preg_replace("/[\x-\x1f]/","",$orig);
echo $dest;
echo "\n<br>\n";
?>
Expected result:
----------------
Should return
IIÏÏïï
in the three alternatives.
Actual result:
--------------
This returns:
II??ïï <--- incorrect
<br>
IIÏÏïï <--- correct
<br>
IIÏÏïï <--- correct
<br>
