Also you can use this:

assuming that you have a fixed size figure such as a pdf page:

\definesymbol[Bsymbol][{\scale[width=1.6ex]{\externalfigure[myfile.pdf][page=1]}}]
\define\mysym{\kern 0.2em \symbol[Bsymbol] \kern 0.3em}

\starttext
this is a sample\mysym text.
\tfa{this is a sample\mysym text.}
\stoptext
