# LaTeX bug or else?

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?

Thanks.

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.
• The original post by fbakhshi was riddled with \unicode{0x200E} characters (LEFT-TO-RIGHT MARK). I removed the rest from YACP's post. – robjohn Jun 25 '13 at 12:38
