DESCRIPTION
These functions implement the C++ interface for the Unicode Canonical Decomposition and Composition [1] , See the description of the underlying unicode_canonical (3) C library API for more information. C++ specific notes:
ā¢ The C++ decomposition reallocate callback receives a single vector of offset and size tuples instead of two separate arrays or vectors. unicode::decompose_default_reallocate () is the C++ version of the default reallocate callback. It receives the receiving the same tuple vector parameter, too. The C++ interface use std::u32strings to represent Unicode text strings, and unicode::decompose_default_reallocate () resize s it.
Like the C callback, the C++ one gets called 0 or more times.
ā¢ unicode::compose () takes care of initializing, applying, and de-initialization the unicode_composition_t object, for decomposition. The callback receives a reference to the unicode_composition_t object, which the callback should not modify in any way.
