unsigned int (*hb_unicode_decompose_compatibility_func_t) (hb_unicode_funcs_t *ufuncs

);
hb_unicode_decompose_compatibility_func_t
has been deprecated since version 2.0.0 and should not be used in newly-written code.
Fully decompose u
to its Unicode compatibility decomposition. The codepoints of the decomposition will be written to decomposed
.
The complete length of the decomposition will be returned.
If u
has no compatibility decomposition, zero should be returned.
The Unicode standard guarantees that a buffer of length HB_UNICODE_MAX_DECOMPOSITION_LEN codepoints will always be sufficient for any
compatibility decomposition plus an terminating value of 0. Consequently, decompose
must be allocated by the caller to be at least this length. Implementations
of this function type must ensure that they do not write past the provided array.
Parameters
ufuncs |
a Unicode function structure |
|
u |
codepoint to decompose |
|
decomposed |
address of codepoint array (of length HB_UNICODE_MAX_DECOMPOSITION_LEN) to write decomposition into |
|
user_data |
