NodeJS 6.4.0 Empty String Range Error

[Buffele]

Hello,

Only affects latest NodeJS (6.4.0) Version. 6.3.1 worked fine.

var sp = require('../schemapack')

var stringSchema = sp.build('string')

var data = stringSchema.encode('')
var decoded = stringSchema.decode(data)

console.log(decoded)

Output:

        return this.utf8Write(string, offset, length);
                    ^

RangeError: Offset is out of bounds

Hello! Looks like there was a change in the utf8Write implementation in Node between versions 6.3.1 and 6.4. I'll make an issue on their Github to see if it's intentional. If so, I'll just patch schemapack to check for strings of length 0 before writing.

The Node.js team confirmed this as a bug. Looks like it will be fixed in their next release. Just use 6.3.1 in the meantime, I suppose.

Can some one send me a client side implementation of schemapack.
