Roger,<br>
I've just tested the UTF8 patch, and yes it also works in my case.<br>
This is great, it seems that all these characters problems (shadow +
accentuated characters) are solved now.<br>
Hopefully, these patches will be included in the next release.<br>
Thanks a lot for your help.<br>

<div>Yes, the problem with accentuated characters is already
solved. Therefore, next VTK release will not have that
problem. However, if you are interested on it now, you can
apply this patch: <a href="http://vtk.org/gitweb?p=VTK.git;a=patch;h=331a44656276882766248c1f8e338434b40226ef" style="color:rgb(53, 66, 88)" target="_blank">http://vtk.org/gitweb?p=VTK.git;a=patch;h=331a44656276882766248c1f8e338434b40226ef</a>.</div>
<div><br>
</div>
<div>Let me know if it works.</div>

I applied your patch to vtk5.6.0, and this fully solve the
shadow problem, great!<br>
Still I 've got this problem with accuentuated characters
(which of course was your patch was aiming to solve). If I
understand well your reponse, this is already solved in the
dev branch, am I correct?<br>

<div>Since VTK 5.2.0, vtkTextActor is rendered using
glyphs instead of OpenGL. I also had that problem
but it was solved in that commit <a href="http://vtk.org/gitweb?p=VTK.git;a=commit;h=331a44656276882766248c1f8e338434b40226ef" target="_blank">http://vtk.org/gitweb?p=VTK.git;a=commit;h=331a44656276882766248c1f8e338434b40226ef</a>
when UTF8 text rendering was enabled. It's after VTK
5.6 was released.</div>
<div><br>
</div>
<div>On the other hand, I suppose you still have
problems rendering text with shadow, as you reported
in that issue: <a href="http://vtk.org/Bug/view.php?id=9618" target="_blank">http://vtk.org/Bug/view.php?id=9618</a>.
I tried to solve it and I attached a patch in that
issue waiting for feedback. It would be wonder if
you could test it and let me know if it works well.</div>

<div>Thanks,</div>

<br>
I am having trouble displaying accentuated
characters in vtkTextActor with vtk5.6.0 under
MS-VC++2005.<br>
Here below is an exemple that reproduces the
problem, by printing the same string than
contains accents "é,è,à".<br>
When I run this small prog, as a result I obtain
that accentuated characters (é,è...) are :<br>
- correctly displayed when used in a
vtkScalarBarActor title,<br>
- not displayed when incorporated in
vtkTextActor.<br>
<br>
Any idea where does this come from and how to
solve it?<br>
<br>
As an additional comment, this used to work
correctly under vtk5.0.x, it is only broken from
vtk5.2.x up to vtk5.6.0.<br>
<br>
Thanks<br>
