 Thanks Tony and Gerald for your replies!

In the off chance that anyone might find this useful, here is the solution I
came up with. 

The first function greps all of the words in the dictionary that _start
with_ the copied characters.

The second function greps all of the words that _contain_ the copied
characters.

--Bill


fun! Findzi()
    exec(':grep " ' . @x . '" e:/cedict/cedict_ts.u8')
    if v:shell_error == 0
        bp
        copen
        exe ":normal \<c-w>w"
    endif
endfun

fun! Findanyzi()
    exec(':grep ' . @x . ' e:/cedict/cedict_ts.u8')
    if v:shell_error == 0
        bp
        copen
        exe ":normal \<c-w>w"
    endif
endfun

:map <F6> <Esc>:normal "xyl<CR>
:map <F2> <Esc>:normal 2"xyl<CR>
:map <F3> <Esc>:normal 3"xyl<CR>
:map <F4> <Esc>:normal 4"xyl<CR>
:map <F5> <Esc>:normal 5"xyl<CR>

:map <F7> <Esc> <c-w>w
:map <F8> <Esc>:w<CR>:call Findzi()<CR><CR>
:map <F9> <Esc>:w<CR>:call Findanyzi()<CR><CR>

Another way of doing it (without involving registers) is the following.

Echo character under cursor
   :echo getline(".")[col(".") - 1]

Echo characters before, under & after cursor
   :echo strpart(getline("."), col(".") - 2, 3)

Hope this helps.
