I can’t figure out how to get the visidata frequency analysis histograms to render properly. Some render as blocks as expected but others are those diamond-question marks. I know it’s a silly hang up but it’s what’s keeping me on iterm. It’s seemingly impossible to search for (or at least I haven’t figured out the right keywords) to troubleshoot too.

Sounds like perhaps your main and fallback fonts are missing the Code Points in question.
I am not a ghostty user, but I think it has a setting for that, if you can figure out which font iTerm2 is rendering those glyphs with.
Try asking on https://github.com/saulpw/visidata the community there can help.
I am seeing this issue on a Mac with ghostty but not with wezterm, from the same binary. Ghostty shows some correct characters and some diamond-question marks, and a line usually contains one or the other. The ghostty inspector shows the diamonds are not the blocks.
