Is there a way to display a vertical arrow character in a linux terminal using ncurses?

I'm trying to reproduce an old GUI screen in my application that uses ncurses for terminal display. The old GUI used characters that looked like this: Up and Down Arrows

Is there a special ASCII code or other mechanism to do this with ncurses?

There are the alternate character set characters ACS_UARROW and ACS_DARROW, which you can display with addch and related functions, but what character they display depends on your terminal type.

If your terminal is unicode aware, your font can display unicode and your locale is set to unicode, you should be able to simply

echo '↑ or ↓'

You can use the arrows in unicode, here you can find a list of unicode arrows and the relative codes.

ncursesw has the support to wide character set, you should just set the locale:

setlocale(LC_ALL, "")
