Exporting fonts properly

[Berta Milan <bertm0am artax karlin mff cuni cz>]

Simple question:

What can I do to export fonts properly (for example to svg)?

I mean: The Dia does not exports properly the sizes of
fonts, they are always set to "font-size: 1" (or if they are
bold, in svg file they are not). How can I export to svg
file and keep adjusted font size and style?

Thank You, Milan Berta
