Scale content to height of the font, measure font height
Hi, I'd like to scale something (actually a symbol drawn in TikZ) to the exact high of the char 'M'. I found the scale environment for it but struggle to measure the correct font height. I found the "definemeasure/measure/measured" commands but they define a dimension and are not for doing measurements on rendered text. Is there a simple way to get the height a char as a dimension? MWE: ``` \starttext % Is it possible to replace 1cm with a common expression? This is the letter M. \scale[height=1cm]{a} should have the exact same size as M. This should also be true {\tfc with a bigger M. \scale[height=1cm]{a}}. \stoptext ``` Best Gerion

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
