In ePAPR v1.1, I could not find any strict requirement. It is just saying: The recommended format is “manufacturer,model”, where manufacturer is a string describing the name of the manufacturer (such as a stock ticker symbol), and model specifies the model number. If I am not mistaking, the stock ticker symbol will not contain exotic characters, but it is not always available. So we should probably add the '-. I am not sure for the '_'.
