I understand why the standalone word 'question' is forbidden in titles; however SE doesn't make an exception for 'question-mark', as in this case, where I was trying to improve the title from:
How to separate data into multiple columns with strange separator using separate()?
to "How to separate data with 5 question-marks separator using separate()?"
The term 'question-mark(s)', and writing a regex to match them, and the fact that they have to be specially handled in regex syntax, was central to the OP's problem, so this isn't just a curiosity.
Ironically, I can rewrite their title with ?????
yet not 'question-mark'. '?????' is undesirable because the SO search engine won't find it; although SymbolHound search engine does
By the way, 'regex' is also forbidden in titles, otherwise this could have been boiled down to 'regex to match 5 question-marks separator'.
[?????]
instead of '[?]{5}`. Anyway, what's your opinion on my point?
