Some special characters are used both in writing and in programming. Unfortunately, the HTML converter (the first step of the XML file creation) sometimes mis-interprets these unless special care is taken. In case of the characters listed in this data frame, the user has to manually substitute the code for the character in the Rmarkdown source.
If something does not work that is not listed here, please try to find the the HTML code for your character and open an issue on GitHub for the maintainer with an example.
