Text Formatting ⇒ roman numeral

[Gunther]

i've searched ages for this, but can't find a satisfying solution. I want to reproduce this symbols:

romannumeral gives a "II" which is too large/not forming one letter:

Code: Select all

\newcommand{\rmnum}[1]{\romannumeral #1}
\newcommand{\Rmnum}[1]{\expandafter\@slowromancap\romannumeral #1@}
$\boldsymbol{J}_{\boldsymbol{F\Rmnum{2}}}$

i guess, it's not done with a command/macro, but with a separate font..
anyone else got some ideas?

thanks a lot,
Gunther

sry about the images, hadn't seen an upload button

anyway, I found a solution and tought I'd better share it:

Code: Select all

\boldsymbol{J}_{\hspace*{-0.5ex}\boldsymbol{F}\hspace*{-0.2ex}I\hspace*{-0.4ex}I}
