I recently saw a question titled "Jquery vs Javascript" (10k+ users only). I thought, "surely someone has asked this question before", and began looking for a duplicate. What I found is a question with the exact same title, just with a little different punctuation and casing. It was "Jquery vs Javascript" and "jQuery vs. Javascript?". The only difference being the ., ?, and the casing.

Since we now disallow questions with duplicate titles, I propose that when checking for questions with duplicate names, certain punctuation be striped out to prevent the duplicate from occurring in the first place.

As pointed out in the comments, if isn't already, white-space and non-printable characters may want to be removed for duplicate detection as well.

  • You might want to add whitespace/non-printing-characters to this request as well, although stripping non-printing-characters prior to title comparison would prevent "those in the know" from getting around the restriction if needed. – cdeszaq Apr 3 '12 at 15:14
  • @cdeszaq I thought about it, but my concern is I don't want the duplicate question block to be too aggressive. That's probably why it doesn't check for these things already. However, I think a small subset of punctuation that is used in English grammar (like commas and periods) would be good to strip. Other punctuation like ^ or * are usually more technical, which could be a very similar titled question, but not the same. – vcsjones Apr 3 '12 at 15:31

    And automatically close and delete some patterns... ;-) – Arjan Apr 3 '12 at 16:42

    @Arjan Wow, for real. Sometimes I think all questions should be closed at time of posting, and have to be voted open. :S – jscs Apr 3 '12 at 18:03
  • @IuliusCæsar, how about these... – ben is uǝq backwards Apr 3 '12 at 20:04

    Err, are you expecting more edits? See also When is “EDIT”/“UPDATE” appropriate in a post? – Arjan Apr 4 '12 at 16:51

    @Arjan I wasn't ruling out the possibly. Thanks, I'll remove it. – vcsjones Apr 4 '12 at 16:52
  • Why stop at closed, @IuliusCæsar? Start all questions off deleted so they have to be approved by 10kers or mods to be seen! (Note to self: revisit this comment when balpha solicits suggestions for April Fools' Day 2013.) – Pops Apr 4 '12 at 17:02
  • Child's play, @Pop. We should wipe the SE hard drives every time a question is submitted. – jscs Apr 4 '12 at 17:09

    Now we're making progress, @IuliusCæsar... but perhaps we should burn the entire data center from orbit on submit. Just to be sure. – Pops Apr 4 '12 at 17:18

    @PopularDemand - You may want to do it on keydown as well, since you wouldn't want any unapproved characters getting through. – cdeszaq Apr 4 '12 at 18:17
  • That may not be thorough enough, @Popular; I suggest releasing nanites to dismantle the planet the next time stackoverflow.com recieves a SYN. – jscs Apr 4 '12 at 18:45
  • If it's thoroughness you're after, @IuliusCæsar, there's always the option of sending a notification to the global inbox of whoever is running the simulation that we call the universe. In that notification, we could request that he perform a backup and reboot/reload. – Pops Apr 4 '12 at 18:52

    Perfect, @Pop! (As long as that entity does not then try to post a question on SU about how to do that... "Getting error trying to reboot my Universix box -- URGENT!!") – jscs Apr 4 '12 at 19:04
