            Bug ID: 122196
           Summary: Weird %Ux.... character handling in starmath editor.
                    Sometimes interpreted, sometimes not.
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: vivien.guillet at laposte.net

Description:
I launch lomath Then I type

  a %Ux003C b newline

in the text editor (%Ux003C is the "less than" caracter)

StarMath then displays the graphic equation

  a%Ux003Cb

(%Ux003C is not interpreted.)

Then, I launch lowriter. In this writer window, I load a document docA
containing equations that use  Ux003C to display the "less than" char.
Everything is right in this document, "Ux003C" appears as "<".

Note that this Ux003C symbol does not occur on the first page of the document. 

Going back to the equation editor, I re-run the starmath parser (by adding a
char, removing the char). Equation stays the same. %Ux003C is still not
interpreted.

But then, I scroll to the equation that use the %Ux003C as starmath code,
scrolling until this equation is onscreen. 

Finally, going back to the equation editor, I add and remove a char again.

And this time, %Ux003C is interpreted by starmath and graphical part shows "a <
b".

Note that if I save this equation, the document now acts as docA as soon as
equation is displayed.

That's weird. 





Steps to Reproduce:
write an equation like a %Ux003C b

Actual Results:
%Ux003C is sometime interpreted, sometime not, depending on other opened
documents.

Expected Results:
I don't even know if %Ux003C should be interpreted, but I rely on some
documents using it.


Reproducible: Always


User Profile Reset: No
