This was added in #24568 to avoid triggering an UNKNOWN_UNICODE input event when SDL sends an SDL_TEXTEDITING event with an empty string.

If commenting out this line fixes the issues, my guess is that the system sends an SDL_KEYDOWN event that is skipped due to being an auto-repeat event, immediately followed by an SDL_TEXTEDITING event which is handled in the same CheckMessage call, therefore overwriting the first event.

I wonder if you could print a log of key events when the issues happen so we can better understand what is happening and make a more specific fix?

Could you describe what's wrong in your test? According to the log, you opened the options menu, entered a default character name, confirmed, and exited the game, but the issues you linked in the original post were about game not responding to auto-repeated keys.

这是我在注释了那一行代码后的输出的日志，如果没有注释掉那一行代码，令函数sdl_keysym_to_curses的返回值不为零的键盘事件的keysym都会使得在KEYDOWN事件后跟随一个TEXTEDITING事件，而这个跟随的TEXTEDTING事件的ev.edit.text长度为0，进而会执行被注释的那一行代码，使得原本的last_input的结果被覆盖掉

也就是说，这个bug会导致tab键、方向键回车键等都无效

TEXTEDTING事件的ev.edit.text为空相当于系统告诉程序把输入法的预览文本设为空，如果只是注释掉这行代码的话，程序根据KEYDOWN和TEXTEDITING两个事件只返回一个input_event，可能导致输入法预览异常。感觉要正确修复比较复杂，可能需要改变SDL_TEXTEDITING的处理方式，不对last_input进行赋值（按理说输入法的预览文本不应该触发输入，不知道原来为啥这里有赋值），并且在根据edit_refresh处理预览文本的时候考虑包括已处理事件的所有事件。

last_input.type = input_event_t::keyboard_char;
}
last_input.edit = ev.edit.text;
