OK, that's what I did, as I described, unless I'm completely not understanding what the "glyph window" is. But, as I said, it only allows entering a 4-hex-digit unicode. But the one I'm after is 5 hex digits.

I believe I am comfortable with this, but unless I'm completely missing something, there is no way to insert a glyph this way other than typing its keyboard character. So for a glyph that has no keyboard character, as the one I'm talking about, there seems to be no way to do it, without going through the Story Editor. Am I missing something??
