Okay, strangerstill, I'm willing to parade my ignorance:
I'm still missing something. I checked out your link, but I can't figure out hgow to get an "&etc" type character to display. If I simply type "&pi", I get --> &pi. Is there some key-chording needed here, as with ASCII?
Also, what character map are you using? The Windows accessory? Using that, p֥ is what I get for "pi root infinity".
