Hello.
In this post I will describe my reasoning.

I think the converter program doesn't need to display the text in the window.
For example, I want to convert the English source code of your solution for the "Write a TextWindow login program" task into text that contains the necessary words in my native language.
I have a universal converter program.
When I run this program, the first thing I do is connect the character sets replacement tables that I currently need.
Then, I specify the English source code file.
The program loads it, automatically replaces the required character sets and opens a dialog box for saving the converted text in a new file.

That's all.
Next, I can use this file as I need.
I can open it in my favorite text editor, which may have the custom syntax highlighting I need.
I can study the logic of the source code myself, or I can explain that logic to other people using text in my native language.

I think that's good.
