Function encoding_c::encoder_encode_from_utf16

#[no_mangle]
pub unsafe extern fn encoder_encode_from_utf16(
    encoder: *mut Encoder, 
    src: *const u16, 
    src_len: *mut usize, 
    dst: *mut u8, 
    dst_len: *mut usize, 
    last: bool, 
    had_replacements: *mut bool
) -> u32

Incrementally encode into byte stream from UTF-16 with unmappable characters replaced with HTML (decimal) numeric character references.

See the top-level FFI documentation for documentation for how the encoder_encode_* functions are mapped from Rust and the documentation for the Encoder struct for the semantics.

UB ensues if encoder is NULL, src and src_len don't designate a valid block of memory, dst and dst_len don't designate a valid block of memory or had_replacements is NULL.
