Advanced formatting is generally not well supported.
The basic formats: bold, italic, underline, left, center or right justified, indentation, quotation, lists will generally work as expected.
Changing fonts, colors, highlights will generally not work right.
You will have to test with your editor and see what you can use and what you cannot use.
