note 48732 added to ref.regex

i'm building a trawler, and about 95% of the words were logged in the database without any problems, however was having big difficulties with whitespace. Anyway, after using trim, eregi_replace and everything, found that the actual code for the alleged whitespace was \xA0 - and was not being picked up by any regex filters such like [^a-z0-9] and also is not classed in [:space:]! i couldnt find a reference to this character on ASCII-hex lists as its quite high up - but if having similar difficulties try http://www.x-ways.net/winhex/index-m.html and download their software (free) to view your php/ text file etc - it worked very well (for me anyway)!! ---- Manual Page -- http://www.php.net/manual/en/ref.regex.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48732 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48732&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48732&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48732&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48732&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48732&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48732&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48732&report=yes Search -- http://master.php.net/manage/user-notes.php
