I have defined a command (mapcommand) to convert a given text into another form. However, in article after using the command it changes the font below of it. I mean, the font remains Times New Roman until I use the command, after using the command it changes font to CharisSil to all the text below of it. I want to use CharisSil font only the text inside the command. I tried \DeclareTextFontCommand but not working properly. Please see the MWE below. Thank you. Compiler: XeLatex
