In this topic I can't see the reason for some indices looks like not being indices. I've done something wrong or is there a LaTeX bug?

Fixed it. For some reason you typed an "empty" character between the underscore _ and the q. So the action of the underscore hit the empty character instead of the letter q.

Removing the zero-width character fixed the problem.

  • $\begingroup$ @YACP: can't blame you for not seeing, since that is the whole point of a zero-width character... $\endgroup$ Jun 25, 2013 at 10:42
  • $\begingroup$ The original post by fbakhshi was riddled with \unicode{0x200E} characters (LEFT-TO-RIGHT MARK). I removed the rest from YACP's post. $\endgroup$
