Hey @XXGUI! 👋 I'm here to help you with any bugs, questions, or contributions you have. Let's squash those bugs together!

I found similar discussions regarding issues with displaying Chinese characters correctly on charts in Dify:

1. The Chinese characters cannot be displayed correctly on the axes of the charts generated by the chart creation tool ^[1].
2. The Chinese characters cannot be displayed correctly on the axes of the charts generated by the chart creation tool ^[2].

These discussions are still open and do not have a confirmed solution yet. However, a related issue with Japanese characters suggested ensuring proper encoding and using a text extraction tool that supports the specific language characters. You might want to check if the charting library or tool you are using supports Chinese characters and if there are any encoding settings you can adjust.
