I am using TeX within MetaPost;  my goal is to print a single
symbol  rho.  My approach is to use the font cmmi10 enlarged
slightly.    However I obtain two additional symbols -- a small  left and
right parenthesis.  The parenthesises are not part of my Metapost program.
  Is there a way to remove these extra
symbols?

I have attached three files;  test.mp,  test.tex, and  test.pdf.

Any help here would be appreciated.
Thanks.    Walt Burkhard
