The ex ":w" command is linewise, regardless of what visual-mode you
were in, so you'll get the whole line.

You might try yanking it and then using the writefile() command

:help writefile()

to write that register out to a file:

:call writefile(@", '/tmp/ch', 'b')

As a further alternative, you might investigate the "ga" &
"g8" commands

:help g8
:help ga

which will tell you further information about the particular
character under the cursor.

Hope this helps,
