Newcommand -- make symbol independent of font size

[Bernt Lie]

Thanks. OK -- then I have to switch to luatex... (I use MikTeX -- does that distribution contain luatex?)

Anyways, I'll defer it to when LyX 2.4 is released. At that stage, I also need to make sure that I can have Unicode fonts in computer listing.

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