推荐答案

您需要有一个名为的setlocale（LC_CTYPE，）; （用UTF-8的区域设置初始化之前ncurses的配置）。您还需要确保你的ncurses实际上是与宽字符支持（ncursesw），但对现代发行版内置这是默认/只建。

You need to have called setlocale(LC_CTYPE, ""); (with a UTF-8 based locale configured) before initializing ncurses. You also need to make sure your ncurses is actually built with wide char support ("ncursesw") but on modern distros this is the default/only build.
