Description:
------------
I want to perform a regular expression on a string to replace all
whitespace and commas with one single space. 
But If the string is a UTF-8 string, this string will be broken.

I was not able to reproduce this behavior on my DebianLinux/Apache1.3.28/PHP4.3.3 Server.
It occurs only on my Windows 2000 machine.

Server: Apache 1.3.28
PHP as Apache Module

php.ini Settings that diff from php.ini-dist:
display_startup_errors = On
magic_quotes_gpc = Off
doc_root = c:/dev/htdocs
extension_dir = c:/dev/php-4.3.3dev/extensions/
upload_max_filesize = 6M
extension=php_bz2.dll
extension=php_gd2.dll
extension=php_gettext.dll
extension=php_mbstring.dll
extension=php_pdf.dll
extension=php_sockets.dll
session.save_path = c:/winnt/temp/php4_sessions
session.use_trans_sid = 1

Reproduce code:
---------------
see http://webpm.woltlab.info/phpgroup/pcre_utf8.phps

Please read also the comments on the regular expression
I can provide more strings that will fail if it is necessary.

Expected result:
----------------
1) Coeur    D?j?   Pris
2) Coeur D?j? Pris

Actual result:
--------------
1) Coeur    D?j?   Pris
2) Coeur D?j? Pris
