I'm using this amazing tex.sx answer tikz star macro for rendering a x-out-of-y stars graphic for my skills on my resumé.
The resume is done with xelatex and exported to pdf. Because it is a resumé, I'm concerned about it being machine readable.
Is there any way to add some alt tag/caption/label/invisible text to the output of the tikz, so it can be obtained when doing copy paste of the pdf?
Also, related question: Is there something like blind friendly latex?
I tried \pdftooltip from the \pdfcomment package, but didn't work out.
