WP Mollom likes your comments
Over the past couple of days, it became apparent that WP Mollom suffers an issue where it “eats” your comment when a CAPTCHA is shown. The result is that only half of your comment is saved. Not good of course. Apart from that, there was also a problem with character encoding.
Of course, this issue needs solving. I could recreate the problem on a testsetup and found the culprit. This issue rears its’ ugly head when a commenter uses double quotes in his/her comment. Because of the way WordPress implements commenting, I have to embed the commentdata in the CAPTCHA form as a cluster of hidden fields. The handling of the encoding was a bit wonky here which causes data to get corrupted.
