### Function

# GLibunichar_fully_decompose

#### Declaration

gsize
g_unichar_fully_decompose (
gunichar ch,
gboolean compat,
gunichar* result,
gsize result_len
)

#### Description

Computes the canonical or compatibility decomposition of a
Unicode character. For compatibility decomposition,
pass `TRUE`

for `compat`

; for canonical decomposition
pass `FALSE`

for `compat`

.

The decomposed sequence is placed in `result`

. Only up to
`result_len`

characters are written into `result`

. The length
of the full decomposition (irrespective of `result_len`

) is
returned by the function. For canonical decomposition,
currently all decompositions are of length at most 4, but
this may change in the future (very unlikely though).
At any rate, Unicode does guarantee that a buffer of length
18 is always enough for both compatibility and canonical
decompositions, so that is the size recommended. This is provided
as `G_UNICHAR_MAX_DECOMPOSITION_LENGTH`

.

See UAX#15 for details.
