This indicates (I think) that the zero-width joiner character is not  
supported in the font you are using, and therefore gets replaced by  
the font's ".notdef" glyph, which you are seeing as a large space.

If I'm right about this, it is a deficiency in the font, and I can't  
think of a good workaround right now. My suggestion would be to select  
a different font.
