Allow to create your own text in 3d, can be easily extruded into a mesh using the Extrude Shape
or if your intent is only to display it with a Surface
then the Triangulate
should be enough.
To display international characters such as Cyrillic / Chinese / Arabic etc. First you must go inside "edit > preferences > application > skin" and change here the skin into custom and the "Fixed Font Choice" into a font supporting your characters (such as Microsoft YaHei for Chinese).
This will allow you to write inside the various text editors.
Now do not forget to change the font of the text layer itself inside it's own parameters.
