enum class byte_string_chars_format : uint8_t {base16, base64, base64url};
```
Specifies byte string formatting.
### Examples
#### Byte string formatting
```cpp
#include <jsoncons/json.hpp>
using namespace jsoncons;
int main()
{
std::vector<uint8_t> bytes = {'H','e','l','l','o'};
json j(byte_string(bytes.data(),bytes.size()));
// default
std::cout << "(1) "<< j << "\n\n";
// base16
auto options2 = json_options{}
.byte_string_format(byte_string_chars_format::base16);
std::cout << "(2) "<< print(j, options2) << "\n\n";
// base64
auto options3 = json_options{}
.byte_string_format(byte_string_chars_format::base64);
std::cout << "(3) "<< print(j, options3) << "\n\n";
// base64url
auto options4 = json_options{}
.byte_string_format(byte_string_chars_format::base64url);
std::cout << "(4) "<< print(j, options4) << "\n\n";
}
```
Output:
```
(1) "SGVsbG8"
