I'm still a bit mystified by all this, but it seems that what characters you can see depends on several things: What kind of browser you are using, what the default font for that browser is (or what font you have changed it to), and maybe on whether the font in question has all those characters defined.

Although it may be fun to put lots of special characters in our postings, I suggest we limit ourselves to those characters that practically EVERYONE can see.

For those people who want to post song lyrics in, say, French, Spanish, or Gaelic, it's nice to be able to use all the accent marks and punctuation marks that those languages customarily use. As long as we stick to those, I think we're safe. To keep Mudcat accessible and intelligible to all, I think that's the ONLY time we should use special characters.

The notes that I inserted in my first message above were meant as an experiment. I see no need to use them, and I don't intend to use them again.
