cursor position off by one; also weird errors when switching to another theme

[hsharrison]

I'm getting a weird issue, that the cursor position is off by one. The cursor appears one position behind where I expect it to be, hiding a letter and messing with my typing. I narrowed it down to the theme because in other themes it doesn't happen.

I feel like something is wrong with my install but I cleared everything and started over and it still happened. I also get these errors when switching from bobthefish to any other theme (until I delete functions/fish_prompt.fish:

I'm having the same issue (#355). Does setting theme_nerd_fonts = no fix it for you?
