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.
