I can't seem to find the UTF-8, latin-1, or HTML encodings of these entities - and I'm not sure how to input the utf-8 or latin-1 even if I do. Does anyone know how to do this?

Does anyone know how to do > this? there's nothing like a blackboard or double-struck R and Z in latin-1 (and ASCII) so you will need to live with a transcription like `R' or `REALS' &c. In unicode these characters are called `double-struck capital r' and `double-struck capital z' and they have the hex values 211d and 2124 respectively. In Emacs you can enter them with `C-x 8 RET 211d RET' or `C-x 8 RET double-struck capital r RET'. The corresponding XML (XHTML) entities are `ℝ' or `ℝ' and `ℤ' or `ℤ' respectively. However, at least latest firefox does not know how to render these and outputs these entities literally so you might prefer to go for a transcription as well or use a unicode page encoding with the appropriate unicode characters. In case you are interested in further blackboard characters, w3c has a nice page about double-struck entities. Find it at http://www.w3.org/TR/xml-entity-names/double-struck.html.

Yes, google... :) The search string `symbol Z "set of integers" utf8' gives you a nice first hit. HTML entities for double-struck capital Z and R are: R: ℝ (decimal), ℝ (hex) Z: ℤ (decimal), ℤ (hex) Latin-1 does not support these characters. Fall back on plain "Z" and "R" or use a description like "[set of integers]". To type in the character in Windows, hold down the Alt key while typing the hex code, e.g. `211d' for R. On the Mac, open the Character Palette and jump to Letterlike Symbols. In Emacs, you can select the Unicode input method with `C-x <RET> C-\ ucs <RET>' Then typing U followed by the hex code, `U211d', will get you the double-struck R.

C-x 8 RET 221d > `---- > > Darlan For those of you that are latex users and who cannot remember all these special codes, one of the best input methods in Emacs is the "tex" mode which allows you to simply type in \alpha to get α or, given the original question, \Bbb{R} or \Bbb{Z} to get ℝ or ℤ. If you "M-x describe-input-method RET tex RET", you'll get all the special key sequences it knows (the same obviously applies to the ucs input method, of course).
