Function encoding_c::encoder_encode_from_utf8

#[no_mangle]
pub unsafe extern fn encoder_encode_from_utf8(encoder: *mut Encoder,
                                              src: *const u8,
                                              src_len: *mut usize,
                                              dst: *mut u8,

Incrementally encode into byte stream from UTF-8 with unmappable characters replaced with HTML (decimal) numeric character references.

The input absolutely MUST be valid UTF-8 or the behavior is memory-unsafe! If in doubt, check the validity of input before using!

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, had_replacements is NULL or the input is not valid UTF-8.
