Version: unspecified (using KDE 4.5.1) OS: Linux Both when I open a plain text file or a lecture I made with ktouch, it allows characters that I can't type with the current layout into the lesson. This means that I can't finish the lesson because it is impossible to type the character. Some of the characters that I have run across that caused problems:Mdash, smart quotes, copyright symbols, etc. Reproducible: Always Steps to Reproduce: Make a plain text file with one of the following characters:Mdash, smart quotes, copyright symbols. Open the plain text file (File > Open Plain Text File) Try to finish the lesson, but notice that you can't since you get the special characters wrong and there is no way to correct them. Make a lecture file with one of the following characters:Mdash, smart quotes, copyright symbols. (File > Edit Lecture. "Create a new lecture", etc). Open the plain text file (File > Open Lecture) Try to finish the lesson, but notice that you can't since you get the special characters wrong and there is no way to correct them. Actual Results: You cannot finish the lesson because it is impossible to type the characters. Expected Results: Not 100% which one of these: + When opening lecture/plain text files, characters not on the keyboard should be removed. + Show how to enter the code for the character with the alt key (or whatever key is used). + Make lecture editor remove characters not on the keyboard layout.
The lesson editor in version 2.0.0 highlights characters not available in the current lesson so there is now an effective QA instrument for this issue for the build-in courses. Version 2.0.0 has currently no feature to train on plain text files (partly due to this issue), so no problem there.
