# al\_utf16\_encode(3)

Allegro 5 API

## NAME

al\_utf16\_encode - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  size_t al_utf16_encode(uint16_t s[], int32_t c)
  ```

## DESCRIPTION

Encode the specified code point to UTF-16 into the buffer `s`. The buffer must have enough space to hold the encoding, which takes either 2 or 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\_utf16\_width(3)](/al_utf16_width/3.md).
