Describe the bug
I'm using btop tool https://github.com/aristocratos/btop/ to monitor my Linux system. This tool is a "modern" version of top/htop to display CPU, memory, processes, disk usage with graphic representation in terminal.
btop uses some graphic characters to print graphs (see code in https://github.com/aristocratos/btop/blob/main/src/btop_draw.cpp).
I have some difference with graphics using Kitty terminal and other VTE terminal (Terminator).
