Is it a good idea to use unicode symbols as Java identifiers?

I have a snippet of code that looks like this:

double ?t = lastPollTime - pollTime;
double a = 1 - Math.exp(-?t / t);
average += a * (x - average);

Just how bad an idea is it to use unicode characters in Java identifiers? Or is this perfectly acceptable?

On Windows 7, dir or tree can't show unicode characters, even starting cmd with cmd /U So I would press Window Key + R to run something, and type in cmd /U so that the content might handle Unicode.
