You could copy it from Character Map, KCharSelect or similar.

Yes, I was surprised to find that there was no "therefore" symbol. I've just done something horrible: type three full stops in a row ... change the middle one to a superscript, and fiddle with the spacing until it looks right!

You can add it to your symbols at: Tools>Catalog>Edit

Follow the Help file: "Edit Symbols"

Thanks for the advice--but I already went to Tools>Catalog>Edit and looked at all 949 symbols, and it really isn't there, at least not on my machine.

You need a font that contains the symbol. I think DejaVu is one of those fonts

Thanks for the link. The whole fileformat.info site looks very useful.

I guess the real problem here is that I hadn't conceived of it as a font issue. I think of '∴' as a common mathematical symbol, and for a formula editor to be really useful it needs to be portable: if I send the file to someone else, it shouldn't rely on their having a non-standard font installed. I had hoped to find a "create symbol" dialogue box, similar to that found in most music notation software, that allows me to put dots and lines wherever I want and save the information as part of the document. Perhaps I'm asking for too much.

Anyway, thanks to everyone for replying. I've got what I need now.

If you can see the ∴ symbol here, your computer has a font that contains it. You can actually copy and paste from your web browser. Use speech marks around the symbol to have it plain (not italic): "∴"

As for the font issue, if you export your document as a PDF, the characters used are embedded. The person receiving the file does not require to have the font installed to display the document properly.

On the computer I'm looking at this site from now (in a public library), that symbol appears as a square, which proves that not all computers do have the correct font to display that symbol.

Of course... I am waiting for the day unicode is truly supported...

On my machine, Lucida Sans Unicode seems to have the therefore symbol included. There are probably other fonts, too. Lucida Sans is a standard font shipped by Microsoft, as far as I know.

You want unicode number 2234.

It's really easy.

Go into insert special character, choose symbol font, and the therefore symbol is the 92nd character.

To add the Unicode symbol for therefore, copy and paste the following (including quotes!):

Code:
"∴"


For those of you who (for whatever reason) cannot use the Unicode symbol for therefore, try the following code:

Code:
.^{size * 2 .}.


I hope that relieves any problems.


edit: Added non-Unicode support.
