NAME
SDL_INVALID_UNICODE_CODEPOINT - The Unicode REPLACEMENT CHARACTER codepoint.
SYNOPSIS
#include <SDL3/SDL_stdinc.h>
#define SDL_INVALID_UNICODE_CODEPOINT 0xFFFD
DESCRIPTION
SDL_StepUTF8() and SDL_StepBackUTF8() report this codepoint when they encounter a UTF-8 string with
encoding errors.
This tends to render as something like a question mark in most places.
