Plot[Sin[x], {x, 0, Pi}, PlotTheme -> "Scientific",
FrameLabel -> {"x (rad)", "Signal (%)"},
BaseStyle -> {FontSize -> 25, FontFamily -> "Latin Modern Math"}]
How can I use two kinds of the font in FrameLabel at the same time?
Like, I want to let "(%)" in "Latin Modern Math" but others are in Times.
