I've seen Greek, Russian and even Arabic written with Latin letters on the internet for convenience. So ss for ß or the other way round is only a minor inconvenience, if even that. By the way, typing ij as two letters is the official way to do it; only in handwriting and occasional signage will you see it written as one glyph. I have no idea why the ij digraph/ligature ended up in Unicode, really.
