調査方針: Start by reviewing the linked comment at https://github.com/PointCloudLibrary/pcl/issues/4717#issuecomment 825855115 which discusses unicode support. Examine the existing tutorial structure in the PCL documentation (e.g., pcl/doc/tutorials/). The goal is to create a simple tutorial demonstrating addText3D with UTF 8 strings, showing both working and non working examples if needed. Check if there are any related PRs or updates in the source code (e.g., pcl/visualization/src/text 3d.cpp) that might affect the tutorial. The tutorial should include code snippets and explanation of how to handle unicode in the visualizer.
