I use them for input text files, and it is not particularly difficult. An efficient method is to use text substitutions, as available on MacOS. The resulting file is UTF-8 with the correct character, and typesetting systems like LuaTeX with ConTeXt or LaTeX/unicode-math translates it into a PDF. It is usually easy to immediately spot if a math style is wrong. Using it in the input makes one more aware of new styles that in the past was not available.
