How to customize your own MarkerShape, for example, using font style?

I need to draw various point symbols on egui_plot, some of which are more complex composite symbols, for example, using styles from font files. How can I achieve this with egui_plot? Or is there any plan in the future to implement this kind of requirement?

我需要在egui_plot上绘制各种点符号，有一些是比较复杂的复合型符号，例如使用字体文件中的那些样式，如何在在egui_plot上来实现？或者未来是否有此需求的实现计划？
