This is to be expected since you are in math mode.  For visualization
you might enjoy org-entities, and for quick typing you may find org's
bindings for cdlatex useful (On my keyboard I get "\Omega" by typing
"¨O", but I customized "¨").

I think LyX does something similar for people with Greek keyboards.
The way LyX does it is *really* annoying since the case isn't right.
Alphabeta may be more cleverer, though.

What's the point of xunicode?  The readme is very sparse, and I
thought xeleatex is always unicode?

The way I would approach the problem is xelatex (or lualatex) and the
package unicode math.  Consider this minimal example, where I don't
even know myself what the math means (mostly I wanted to show
\mathbb{1}, one of the greatest benefits of unicode-math)

    $Ω≔\mathbb{1}\{∀ πᵢ ∈ Π\colon πᵢ = f(p_{i})\}$

As you can see you can nicely mix unicode symbols and "classic" LaTeX.
Unicdode-math supports an abyss of symbols.  See "texdoc
unimath-symbols" (in your shell when texlive in installed)
