Why has the VT Win project such a huge size?

A VT Win project which had a size of a few MBytes becomes after storing more then ten time bigger (100-200MBytes).

Problem
The size of the project increase after storing to a really hughe size.

Reason
If unicode fonts are used which are not present in the PC the project can become so big because each character has to be stored as bitmap.

Solution
Check the fonts you are using and change to a font which is installed on the PC.
