            Bug ID: 357822
           Summary: Superscript characters sometimes not displayed
           Product: okular
           Version: unspecified
          Platform: Kubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org
          Reporter: felix.reuning at arcor.de

In some documents the superscript characters sometimes (in some specific
locations in the text) are not displayed. E.g. if you have a mathematical
expression like x² the squareroot "2" is invisible. Problem is reproducible. 
Same document on Windows with "acroread" or "gv" on linux is correct displayed.
Same wrong behavior with "Evince", but not with "gv" as already mentioned.
Example document is available. Do not know how to provide the document on this
KDE bug tracking plattform ?

Reproducible: Always

Steps to Reproduce:
1. Open critical document
2.
3.

Actual Results:  
y = 0,025x – 0,9x +6.


Expected Results:  
y = 0,025x² – 0,9x +6.


Version 0.23.2
Using KDE Development Platform 4.14.13
