It's not Greek, Chinese or Japanese. It's obviously not Latin. It's not "mushed together" enough to be Arabic, I'm also pretty sure it's not the "alphabet" from Sanskrit, Hindi, etc. (whatever it's called) or Thai.

I'm not an expert in these matters, but I haven't seen anything like this at all, are you sure they're actually letters? Any clue at all where the symbols are from?
