# al\_utf8\_encode(3)

Allegro 5 API

## NAME

al\_utf8\_encode - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  size_t al_utf8_encode(char s[], int32_t c)
  ```

## DESCRIPTION

Encode the specified code point to UTF-8 into the buffer `s`. The buffer must have enough space to hold the encoding, which takes between 1 and 4 bytes. This routine will refuse to encode code points above 0x10FFFF.

Returns the number of bytes written, which is the same as that returned by [al\_utf8\_width(3)](/al_utf8_width/3.md).

## SEE ALSO
