Recently, I've posted a question with ... (three dots in a row) at the end of the question title. To my surprise, it was removed. I tried re-editing it into it, but it just got removed again.

Trying to edit in ...

it doesn't show up in the title

Result: No ... in question title

What and why exactly is preventing me from typing ... at the end of a question title?


Apparently, using <space>... works. The ellipsis character works fine.

For reference, the site I was trying to post this on was Programming Puzzles & Code Golf, where my question/challenge was perfectly clear and valid, and the faux-ellipsis was used for decorative effect.

    Why would you want to? How would it help your question be clearer or easier to find?

    There's a system in place to automatically 'correct' low quality titles. The details should be somewhere here on Meta.

  • I couldn't find it, but I'm on mobile so it was hard to search. May give it a try later today.

    Looks like you can end a question title with an ellipsis character at least on MSE. See edit history of this question. Dec 25, 2016 at 13:07
  • I think a question title should always end in a question mark.

    @PolyGeo The site he/she is trying to post to is code golf. The "questions" there are more challenges than actual questions AFAIK. Dec 25, 2016 at 13:37
  • @MartinSmith there was no mention of Code Golf in the question body so the involvement of that atypical site was only discernible by following a link which I didn't.

  • Regarding your edit it is nothing to do with the space, the ellipsis character is a single character. This is different from typing three dots. Dec 25, 2016 at 14:03
  • @MartinSmith Aplologies, I thought it was three dots.

    @PolyGeo, a question can be a "bug". Dec 25, 2016 at 15:07
  • @alldani I'm yet to see a "bug" that cannot be titled in the form of a question.

  • It probably always can, I'm saying at times it works without too. Dec 26, 2016 at 10:31

1 Answer 1


In 2011, somebody brought this up on this site for the first time that I can find.

This answer says:

The logic for trailing punctuation re-writing becomes.

  • Multiple ? collapsed into one
  • Multiple . collapsed into one
  • ?! and similar collapsed into ?
  • Spaces before trailing punctuation removed (with one exception)
  • Everywhere but the trilogy, multiple ! collapsed in one

Your question title seems to fall under rule #2: "multiple '.' collapsed into one". If you want to disable this for the whole site of Code Golf SE, you should probably make a feature request for that.

Note the exception referenced in "trailing punctuation removed" is French Stack Exchange, for which that rule was disabled. That was because French grammar required/preferred the extra space before the punctuation.

  • Most likely a combination of the 2nd and 4th rule. I'm honestly not sure about that, it's probably an undocumented removal of <space>. or something.

  • @Martin ah, thanks for the edits.

  • There is at least one missing rule. If the title ends in "etc." it will incorrectly be replaced by "etc" Dec 26, 2016 at 14:18
  • @PeterMortensen yeah, OP had a now deleted comment about that. My best guess is that it's a combination of the 2nd and 4th rules.
