The underscore (low line) U+005F is TeX's usual marker to introduce a  
subscript, and is only permitted in math mode; that's why it is  
complaining of a missing $ (math mode switch).

If you want _ to be a regular printable character, and don't care  
about using it for subscripts in math, you can simply say


to switch it to category "other". (See The TeXbook for full details of  
character categories, etc.)
