'How to convert Protobuf ByteString to an octal-escaped String in java?

Could anyone please let me know how to convert protobuf's ByteString to an octal escape sequence String in java?

In my case, I am getting the ByteString value as \376\024\367 so, when I print the string value in console using System.out.println(), I should get "\376\024\367".

Many thanks.

Normally, you'd convert a ByteString to a String using ByteString#toString(Charset). This method lets you specify what charset the text is encoded in. If it's UTF-8, you can also use the method toStringUtf8() as a shortcut.

From your question, though, it sounds like you actually want to produce the escaped format using C-style three-digit octal escapes. AFAIK there's no public function to do this, but you can see the code here. You could copy that code into your own project and use it.
