# SDL\_iconv\_wchar\_utf8(3)

Convert a wchar\_t string to UTF-8.

## NAME

SDL\_iconv\_wchar\_utf8 - Convert a wchar\_t string to UTF-8.

## HEADER FILE

Defined in SDL3/SDL\_stdinc.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**#define SDL\_iconv\_wchar\_utf8(S)     SDL\_iconv\_string(***UTF-8",***WCHAR\_T***,***(char***\*)S,***(SDL\_wcslen(S)+1)\*sizeof(wchar\_t))**

## DESCRIPTION

This is a helper macro that might be more clear than calling

**SDL\_iconv\_string**\
  directly. However, it double-evaluates its parameter, so do not use an expression with side-effects here.

## RETURN VALUE

Returns a new string, converted to the new encoding, or NULL on error.

## AVAILABILITY

This macro is available since SDL 3.2.0.
