Yes, of course. If the FreeType API were based on UTF-16 (like the
"wide" variant of the Windows API, for example), then non-BMP characters
would need to be accessed through surrogate pairs. But since the
FreeType API is based on UTF-32 (I am glad it is), non-BMP characters
can be accessed directly. That's good news.
