[Scribus] question about superscripts

[Cor Pernot]

Hi,

I have a question about making superscripts, i.e. for reference purposes.
For this reason I use the superscript button in the text editor. This works in 
the text editor, here I can see the superscript raised and in a smaller font.
But if I have a look in the exported pdf file, I only see a raised character 
but not in a smaller font!
Using a smaller font for the superscript does not result in a nice solution 
because the number of points that the character is raised, also decreases in 
this way.
Does anyone out there have a solution for this?
(I am using Scribus 1.2.2cvs and the font family I am working with is Lucida 
Sans)

Tanks in advance
