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