Single character mathtext treated as regular text
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Rendering a string such as "x
" via the default vtkTextRenderer with mathtext enabled will pass the string through vtkFreeTypeTools instead of vtkMathTextUtilities. This looks like a regex bug in the parsers.
A work around is to add whitespace between the $ (e.g. "
x $"). The extra space is ignored by the mathtext renderer but triggers the mathtext detection.
