content: At risk of being "one of those guys"; it looks to me like smileys in the forum are a little icon in some folder with some associated free text. When rendering, the icon is substituted for the text.If I'm right, a simple smiley that insertswould serve two functions, and be easy to implement. Primarily it'd prompt people to remember that slash dollar are the escape characters to initiate \$\LaTeX\$, but it's also a handy short cut.

content: At first this didn't make sense, having symbols for emoticons, but now I get that it could be useful.If someone has a list of useful symbols in the appropriate size then I can add them.Omega would be :ohms:

content: I was actually thinking of functionality similar to the url button; it inserts text that you can then edit as desired. It saves a bit of typing, but more importantly it shows the syntax if you've forgotten it. In my imagination an ohms button would literally insert the characters ""I referred to smileys, because they appear to be a shortcut to insert some text and are apparently not too hard to create.I would use latex a lot more if I didn't have to re-research how to use it every time.Anyway, I also see no reason to have a static gif shaped like omega. It's only useful if it fits in with the text.

You can't always rely on Latex because it might be blocked by some firewalls: I'm at work at the moment and just see code.I'd also recommend SVG but the forum doesn't seem to support it. Below I've tried using image tags to display an SVG of the Omega symbol but it doesn't work.

content: Every major browser has handled Unicode adequately for many, many years now. (And your browser charset setting matters only for pages that don't declare the charset used, which is now rare, and violates the HTML standard.) It's flabbergasting that this forum is still limited to some 8-bit character set somewhere in the toolchain, and it's equally flabbergasting that more effort has gone into hackish workarounds than a proper fix.Getting Unicode fixed once and for all would not only allow for Greek characters (and phonetic, and other foreign and symbol characters) to work, but emoji as well on any halfway recent OS.
