This is not possible in unicode plaintext as far as I can tell, since Unicode doesn't allow overstriking arbitrary characters over each other the way more advanced layout systems, e.g. LaTeX do. It is however possible to engineer a font to arrange those characters like that by using aggressive kerning.
