There is nothing simple about loading OTF fonts; luaotfload contains more than 10000 lines of code.
But what I mean with making the file robust is protection against catcode changes, using LaTeX if it's available, disabling loading the file twice, and so on.

Yes, but languages have little to do with input any more once you use Unicode.

polyglossia requires XeLaTeX, it doesn't work with plain LuaTeX or LuaLaTeX.
BTW, you should _not_ do something like replacing ^c by ĉ. If you want ĉ, type ĉ. Use a keyboard layout that contains that character, an input method, or some auto-correction function of your text editor, but don't transform text while processing. This is true no matter whether you write text files, HTML, TeX, or whatever. Babel-like shorthands are completely obsoleted by Unicode and cause more problems than they solve.
