This is because the binary encoding is not really binary. createReadStream uses the same encoding parameters that accepted by Buffer. From the Node Buffer Docs: 'binary' - A way of encoding the buffer into a one-byte (i.e. latin-1) encoded string. The string 'latin-1' is not supported. Instead simply pass 'binary' to use 'latin-1' encoding. Just set encoding to null to get the raw stream or ... In any reference to 'modified' binary, we are talking about running the node binary without the return ret; line, and instead with the replaced return true;. Excess Drag on Garbage Collection. Let's take a look at a quick benchmark. Using the same example from above, we ran a few time trials to get a median time for both binaries. var options = { encoding: 'utf16le'}; var wstream = fs.createWriteStream('foo', options); // OR add the encoding to each write wstream.write(str, 'utf16le'); Writing binary file. Writing a binary file is just a matter of using Buffers rather than strings for the write. Aug. 4.
