# SDL\_INVALID\_UNICODE\_CODEPOINT(3)

The Unicode REPLACEMENT CHARACTER codepoint.

## NAME

SDL\_INVALID\_UNICODE\_CODEPOINT - The Unicode REPLACEMENT CHARACTER codepoint.

## HEADER FILE

Defined in SDL3/SDL\_stdinc.h

## SYNOPSIS

```
#include "SDL3/SDL.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.
