They are organized into seven classes based on their role in a mathematical expression. But if we want accents and other special characters to appear directly in the source file, we have to tell TeX that we want to use a different encoding.There are several encodings available to LaTeX: 1. In that case they can be created with the following command: Wikipedia has related information at Unicode input. Sometimes, the output doesn’t come out the way some of us might expect or want.
