This kind of fancy terminal manipulation is usually an accessibility nightmare.
Real GUI frameworks usually provide semantic information to the OS, which allows screen readers to determine that a given control is a progress bar that is 50% filled, and then render that information by playing an appropriately-pitched tone. In a TUI, all they get is a line of fancy symbols changing quickly, with no context as to what those symbols mean. Same for i.e. ncurses based menus. When programs use colors to signify which menu option is selected, screen readers usually get lost.
Screen readers specifically designed for text-based systems (such as DOS) usually had ways to work around this issue, but modern, GUI-focused ones don't really offer those options any more.
