AutoCad 2D :: Linestyles With Text Not Displaying Properly?

We use linestyles for utilities such as w for water, s for sewer etc. linestyles look like --w--w--w--w--. in Autocod 2004, if you reverse direction of line or rotate line 180 degrees drawn with this linestyle, the w's would look like m's because text reversed with line (this is what i want to happen) in Autocad 2012 and 2013, when i draw a line with the same linestyle, the text will not reverse, even if i manually rotate the line 180 degrees, the w still reads w and not m. is this a system variable, mirrtext did not work.
