elaby | Yet another computer question

I need a new LJ client. The one I have doesn't let you get to your history O.o

Anyway, that wasn't my question. I believe that the little heart character (which I can't find ANYwhere how to reproduce) that people often use in LJ posts (

starandrea in particular lately) shows up in my browser as a line like | only bold.

Does anyone know how I can remedy this? Is it a Firefox thing? A Mac thing? I can see them on my PC with Firefox, but that may be a different version or something (certainly it's the Windows version, but maybe a different edition).

Weirdness. I miss those little hearts!

[edit: Thanks to the commenters, I've figured out now to find the character palette, so now I can use ♥ if I want. Still not sure how to see the ones other people use, but this is certainly a start :)This is also how I'd find accented letters like é, which is good to know.]

[edit part 2: Well, I can see the heart if I'm editing the post, but not when it's actually showing up on my f'list. Huh.]
