No, that one is used for rewinding the stream afaik. But it should be
fairly easy to modify your Lexer to keep track of the character/byte
offset in the file. I'm not completely sure where, but there is some
place where the Lexer increases the column count by one. 

Just override the method and add another field ('offset') and increase
that one too, but don't set it to zero on a line break. Should do the
trick.
