FWIW, if you're okay with editing website source code, you could tell MathJax to render the page with image fonts instead of webfonts (you'd need to set a breakpoint in the config call to MathJax and edit the renderer before the page loads; I've had no success trying to change parameters and then re-rendering the math on the page). After that all MathJax math on the page consists of little images, which transfer pretty good into Evernote. I don't need it often enough to warrant trying to come up with some JavaScript code that automates it, so it's a bit ugly, but it does work. Yaisog
