I've found that comments have a restriction for minimum comment length. I.e. it's impossible to post too short comments.

Yet in the same time this can be overcome with using formatting. For example, simple Question fail comment is too short while _Question fail_ is not (added 2 symbols - actual length increased while comment have same content when it is displayed).

Here is a question about @username in comments and here - about "overcoming" minimum length, but they still aren't focused on formatting issue.

Is it a bug? Should comment length be counted without paying attention to formatting? (since we're able to show them properly, why do not count real, meaningful comment length - note, this has nothing to do with other special characters, like single _ or similar, only formatting)

  • Don't think it's a bug, but agree that adding at least server side validation to actual final length is a good idea. Commented Oct 23, 2013 at 12:35
  • Well then people will just use zero width spaces... I don't think there's much point in doing this. Commented Oct 23, 2013 at 12:46
  • @Qantas94Heavy exactly my point :p

  • @ShaWizDowArd I think it is a bug. Not necessarily an important one, but I'm pretty sure the intent of the minimum length feature is to ensure comments have a minimal visible length, which is clearly not being achieved in all cases. Commented Oct 23, 2013 at 12:58
  • @Qantas94Heavy so such things should be cough too. I.e. if some symbol 'has no length' is shouldn't be counted in comment length.
