in train_word2vec change output="test.vectors" to output = "test.bin" about wordvectors

[bmschmidt]

Yeah, I should really wrap this in a try-catch--I've had several people hit this problem after upgrading. Starting a new issue for that.

I'm pasting the original version below for the archive because I think people tend to find these by googling error codes.

After running prep_word2vec successfully I get the following error. Tried using cookbook data and got same error. 

Am using R version 3.3.1 (2016-06-21) -- "Bug in Your Hair"

Error in type.convert(data[[i]], as.is = as.is[i], dec = dec, numerals = numerals, : 
invalid multibyte string at '(<83>;А;��{{V�:qE;ףv:<9a><99>]9(lc�;'
