Are there any such placeholders in your language modeling data and your 
parallel training data?  If not, all the models are going to treat them as 
unknown words.  In the case of the language model, it doesn't surprise me too 
much that the placeholders all get pushed together, as that will produce fewer 
discontiguous subsequences, which the language model will prefer.
