    Description

      It seems Qt does not detect ZWNJ characters on Persian keyboards.

      Steps to reproduce:
      1. Switch to Persian keyboard layout
      2. Type a character, e.g. <g>
      3. Type <Shift+Space> to input a ZWNJ (alternatively <Ctrl+B>)
      4. Type a second character, e.g. <g>

      Result: The two characters are joined. The ZWNJ is apparently missing.
      Expected result: The two characters remain separate because there should be a ZWNJ in between.

      This is not a problem of displaying. If I copy the character sequence into e.g. a QLineEdit, the result is correct. I suspect that Qt does not handle the input of the ZWNJ correctly.

      Note: I'm not a Persian user myself. This is an upstream report from http://sourceforge.net/p/texstudio/bugs/1127/
