Description

Node.js had a bug in versions 8.X and 9.X which caused buffers to not be initialized when the encoding for the fill value did not match the encoding specified. For example, &#39;Buffer.alloc(0x100, "This is not correctly encoded", "hex");&#39; The buffer implementation was updated such that the buffer will be initialized to all zeros in these cases.
