Bug report for https://thai-notes.com/typing/typingtrainer.html

[kytrinyx]

I've pasted a screenshot from Lesson 18 of the typing trainer below. This is just an example—all lessons that mention a special character have the same issue in my browser, where it shows two small vertical rectangles instead of the character.

This isn't a big deal (I can just try typing it to see what it does), but I figured it's worth mentioning.
