I find using these glyphs really helpful for keeping my code readable, and I've continued to find useful glyphs since posting in 2019. Here's my current list, for anyone interested. They're all tested for decent readability within Fusion. I use these in group names, comments, frame names, and sometimes altVal names. Not all work in the expression editor (those that don't won't break anything but will be displayed as squares in the Expression Editor). MFA attached.
