Why is the image blurred when oponed within nvim's terminal?

[ChenZhongPu]

I am using kitty on macOS, and chara works perfectly.

However, it becomes blurred if I use toggleterm.nvim in Nvim:

How to solve this problem?

Hi, thanks for reporting this. It's happening because the Neovim terminal doesn't support raster graphics. Therefore we emulate it using Unicode characters. If you'd like better graphics support, you should contact the Neovim authors, though note that this would be a lot of work to implement.
