Function encoding_c::decoder_max_utf8_buffer_length

#[no_mangle]
pub unsafe extern "C" fn decoder_max_utf8_buffer_length(
    decoder: *const Decoder, 
    byte_length: usize
) -> usize

Query the worst-case UTF-8 output size with replacement.

Returns the size of the output buffer in UTF-8 code units (uint8_t) that will not overflow given the current state of the decoder and byte_length number of additional input bytes when decoding with errors handled by outputting a REPLACEMENT CHARACTER for each malformed sequence or SIZE_MAX if size_t would overflow.

Undefined behavior

UB ensues if decoder is NULL.
