How do I insert double struck (blackboard bold) characters into a Google Docs equation?

Dear Forum,

I'm looking for a way to insert double struck (also known as blackboard bold) capital E into my Google Docs equation. Link [1] suggests the latex form should be \mathbb{E} (to get a double struck E, the expectations operator), but this doesn't seem to work in my Google Docs (Firefox 3.6.13). I can also copy-paste some double struck characters from sources such as link [2] which have the unicode characters, but this doesn't seem to include a capital E.

Any suggestions anyone?

Rob

One may find the double struck C, H, N, P, Q, R and Z under Symbols > Math in the special characters menu, but the general mechanism isn't available. One cannot change the font inside math mode, and the most painful aspect of that is that one doesn't have the roman font. It is needed all the time in applied science, notably for physical units in formulas and for subscripts that are a normal word (T<sub>in</sub>, T<sub>out</sub>; N<sub>boys</sub>, N<sub>girls</sub>). Regular bold is often used in physical science literature for vector quantities and one can't have it, except the idiotic way one character at a time through the special characters menu. Less important, sans serif bold might be used for matrices and operators. The double stroked "poor man's bold" is in good company in being omitted from the GDocs equations editor.

Thanks for your heartfelt response Bas. Let's enjoy the fact that, just for a moment at least, we're sharing our suffering...
