Dear Edvin, Guilty is far too strong. Your intentions were fine.

The symbols do appear correctly when someone copies and pastes your code back on into a notebook.

However, when coding in mathematica, I seldom use symbols and subscripts. I find waveFunction to be easier to read and less prone to error than $\psi$, angularFrequency to be better than $\omega$, mass to be a better symbol than M, and accell to be a better symbol than A. It self-documents to use longer variable names. Symbols are a remnant of physical typesetting and paper....

Those that would give the best answers to questions work quickly and aren't likely to type out an expression. They likely test the result for syntax by evaluating code. I am raising this point as an attempt to be helpful.
