+1 to what Francois said. You either want to use the method that takes a
length or string_view for this case:

I would say at first sight that it's due to your usage of char[] and
builder.Append(d) implicitly does a strlen.

Sure!
BinaryBuilder builder;
char d[] = "\x00\x01\xbf\x5b”;
(void)(builder.Append(d));
std::shared_ptr array;
(void)(builder.Finish());
int32_t dataLength = 0;
auto aarray = std::static_pointer_cast(array);
const uint8_t* data = aarray->GetValue(0, );
data = aarray->GetValue(3, );

Hello,
According to the documentation BINARY is "Variable-length bytes (no guarantee
of UTF8-ness)”. However in practice if I embed 0x00 in the middle of a char
array and Append it to a BinaryBuilder the 0x00 is converted to 0xff,
everything after it is not appended and the length is computed
