<div>Hi, <br>Thanks for your answer.</div>
<div>I've uploaded the images there:<br> vtk5.0.4 : <a href="http://imageshare.web.id/images/z1t2jtdrbpv7ojvp7k0g.jpg">http://imageshare.web.id/images/z1t2jtdrbpv7ojvp7k0g.jpg</a><br> vtk5.4.2 : <a href="http://imageshare.web.id/images/ezy0ff8fbjifnt739qz.jpg">http://imageshare.web.id/images/ezy0ff8fbjifnt739qz.jpg</a></div>
<div>and I will fill a bug report<br>Cheers</div>

problem but now<br>with vtk5.4.2 (was vtk5.2.1 in the previous post).<br>I was hoping that this problem would have disappeared in the latest release,<br>unfortunately this is not the case.<br><br>Here is a small description again:<br>
<br>I'am trying to upgrade from vtk5.0.4 to vtk5.4.2 .<br>I end up with two problems when rendering vtkTextActor.<br>Basically :<br>- the shadow property looks rather strange in 5.4.2 (and 5.2.1) compared to<br>5.0.4<br>
- accuentuated characters (é, è...) are no longer displayed in 5.4.2 (and<br>5.2.1)<br><br>Note : all vtk version were compiled with VC++2005 under WinVista, with the<br>same options.<br><br>I can hardly believe that I am the only one that is having this problem,<br>
although I admit this occurs only with non standard characters<br>(accentuated).<br><br>So my question again:<br>- any idea where this behaviour change comes from?<br>- any hint to solve it?<br><br>Thanks in advance<br><br>
