I have imported this image from inkscape SVG. One of the characters have wrong fill in the letter. I am fairly new to blender. Is it possible to fix it?
Clean up your drawing, the SVG file is not properly sanitized, there are overlapping segments and residual segments in your spline
There is a small circle overlapping the inner part of your R letter, it is causing letter fill rendering to fail.
