use lualatex and unicode-math. Write into the preamble

\usepackage{unicode-math}
\setmainfont{XITS-Regular.otf}
\setmathfont{XITSMath-Regular.otf}

\newcommand\plimsoll{\ensuremath{\scriptscriptstyle\circlehbar}}



then the following will work:


H${}^{\plimsoll}$ $G^{\plimsoll}$

\Huge
H${}^{\plimsoll}$ $G^{\plimsoll}$
