Improving char spaces
Current way of importing text has some problems with spaces between chars - they are counted in the way that not always works correctly. Sometimes there are spaces in places we don't expect and other time there don't occur in places they should be.

I estimated that the value 0.6 is the most appropriate.
Here is an example of imported pfd file and spaces:
