It was suggested that I re-post this question in this forum:
"I've noticed that I can't copy/paste into and out of boxnotes without characters like double-quotes and double-dashes (" --) being turned into some other identical-looking character. So if I copy/paste something like a curl command with all of those things, it's so mangled (though it *looks*) the same, it causes errors and I end up erasing and re-typing all the non-alphanumeric characters every time. Has anyone else experienced this? It's a small time-suck I'd love to have a workaround for!"
