<div dir="ltr">Hi there,<div><br></div><div>First off, sorry for the late reply! The holidays have created a bit of a backlog ;-)</div><div><br></div><div>While most of the text rendering classes have been adapted to use the new text engine, vtkVectorText is a bit different. Rather than rendering glyphs to an image buffer like the other classes, it uses a hardcoded set of polygons that are used to produce renderable text as polydata. From the vtkVectorText documentation, it only supports</div>
<div><br></div><div>"...the ASCII alphanumeric characters a-z, A-Z, 0-9, [and] ASCII punctuation marks. (The supported ASCII character set are the codes (33-126) inclusive.) The only control character supported is the line feed character '\n', which advances to a new line."</div>
<div><br></div><div>The good news is that the vtkTextActor3D class provides similar functionality (rendering text to a arbitrarily oriented 3D plane), although it will not produce polydata that can be used by other filters. I suggest using this class as a replacement for vtkVectorText if possible. Other pro-unicode classes that might be useful are vtkTextMapper and vtkTextActor.</div>
<div><br></div><div>As an aside, you no longer need to directly interact with vtkFontConfigFreeTypeTools to use a custom font. Newer versions of VTK have a VTK_FONT_FILE symbols that can be used in vtkTextProperty to indicate that a specific font file should be loaded and used. See the TestChartUnicode test for an example of this:</div>

<br>
I know that we can use our own system/custom fonts in VTK now using<br>
vtkFontConfigFreeTypeTools. I want to set some text to vtkVectorText but<br>
with my own font style. Can someone tell me how to do this? Thanks in<br>
advance.<br>
