Webfonts have whitespace below the baseline

I have a problem with webfonts and padding as the type has a white space gap below the baseline that prevents me from applying an even padding around the text. Help please!

I don’t see a difference between old and new in the picture. That space is the descender. You don’t want to get rid of that.
