One of my recent questions on Programming Puzzles and Code Golf, titled ☁ A Little Cloud ☁, was renamed in an edit to Little Chandler is sad. Draw him a cloud to cheer him up. I don't mind the title change, but I am curious as to the reasons why it was changed. Was it because of the Unicode characters? Or something else? I was hopeful to create a series of challenges based off Dubliners, but if there is something wrong about using the titles of the short stories as challenge titles, I would like to know.
In particular, is there a full set of rules or guidelines available for what sort of titles are allowed?
This was originally asked on PPCG meta, but I was redirected here, as it was a SE dev that made the change, allegedly because the Unicode was showing up on Hot Network Questions.
