"Words to censor:" textbox filled with error, the PHP implode failed due to invalid args!

I would like to report a bug on this plugin.
I tried your plugin with a custom list of words, some of them accented ones (french swear words, some containing/ending with "é"...)
it turns out that the bad word isn't censored.

Seems like there's a problem using preg_replace with UTF-8 chars but i have no further explanations so far.
Will post back here if i found a solution for that, but i'd appreciate anyone who's aware about this giving some tips on how to fix the issue.

Cheers!

I haven't tried it out though, so can't say for sure...

Thanks

Thanks again!

for($i = 0; $i < sizeof($words); $i++) {

In some versions of PHP, that sizeof (count) will be executed on every pass in the loop. Do it once outside the loop.

if(in_array($tag->name, $words))

in_array is horribly slow - do an ISSET instead against keys which is incredibly fast - prep the array by doing an array_flip during the plugin init (ie. $words=array_flip($word);

If someone wanted to be clever, they could just look at the list of forbidden words in the plugin directory directly - then just do a variant. Only ways around this are storing the words.txt outside the webroot (difficult given how many people dont know how to do this) or store it in the db options as a serialized list and edit from the admin panel.
