[Paraview] 3.10.0-RC1: state file unreadeable when a Text source contains the degree symbol

[Richard GRENON]

Hello.

Here is a minor problem with Text sources in PV 3.10.0-RC1. When adding 
a Text source in the 3D view with the "degree" symbol "°" (SHIFT right 
parenthesis on the french keyboard) and saving the pvsm state file, the 
state file becomes unreadable. Following is the error message:
>
> ERROR: In 
> /home/kitware/Kitware/ParaView-3.10/source/VTK/IO/vtkXMLParser.cxx, 
> line 483

> vtkPVXMLParser (0x170ad620): Error parsing XML in stream at line

Here is a part of the saved pvsm file about the Text source:
>     <Proxy group="sources" type="TextSource" id="4875" servers="1">
>       <Property name="Text" id="4875.Text" number_of_elements="1">
>         <Element index="0" value="Plan x = 30 - Angle = 15°"/>
>       </Property>
>     </Proxy>
Removing the "°" symbol following "15" makes the file readable.
Other special characters (letters with accents such as é or è ) don't 
have such a problem.

Regards.
