# [NAME](#NAME)

fcft\_precompose - pre-compose two wide characters into one

# [SYNOPSIS](#SYNOPSIS)

**#include <fcft/fcft.h>**

**bool fcft\_precompose(**

**const struct fcft\_font \*font,** **uint32\_t base, uint32\_t comb,** **bool \*base\_is\_from\_primary,** **bool \*comb\_is\_from\_primary,** **bool \*composed\_is\_from\_primary);**

# [DESCRIPTION](#DESCRIPTION)

**fcft\_precompose**() composes the *base* and *comb* wide characters into a single wide character. For example, **L'a'** + **L'\\u0301'** can be combined to **L'á'**.

If *\*\_is\_from\_primary* are non-NULL, they will be **true** if the corresponding wide character exists in the primary font. If **false**, it does not exist in the primary font and **fcft\_codepoint\_rasterize**() will pick the glyph from one of the fallback fonts.

# [RETURN VALUE](#RETURN_VALUE)

On success, **fcft\_precompose**() returns a composed wide character. On error, **(uint32\_t)-1** is returned.
