Overlapping Characters in markup

[Br. Samuel Springuel]

If I wish to create a markup command that combines two characters from 
different fonts (the normal Roman font of the file and another font 
which provides special glyphs) in an overlapping fashion, how would I go 
about doing that?

Thus far I have the following which has both characters, but no overlap:

%%%%%%%%%

\version "2.19.53"

\markup { V { \override #'(font-name . "greextra")  } } }

%%%%%%%%%%%

Note: Since most of you likely don't have the font I'm trying to pull 
the special character from, I've attached it.

Also, it should be noted that I am aware of the unicode character ℣. 
The font I've chosen for this project does not have that character in 
it, hence why I'm trying to fake it.
