(1) Sub- and superscripts Windows & (2) deploying programs
To me this method of using a static compilation seems unnecessarily difficult; the compilation takes half a (working) day and (at least here) it often fails.

why do you want to deploy Qt Creator? It is only the editor and your application don't need it.
. I'll try the solution with html; if it is working we can use this on Windows/OSX/Linux (in the latter two we were also missing e.g. a superscript "3", so using html will sove some additional problems).
