Make legible text

hi,
I read succesfully the tutorial: text in flash: make it legible.
the trick is to use dynamic text.
Fine.
**BUT **To keep the size of the file small I select a specific range for the characters. If I do this, the text is not as legible as if I was not selecting the characters range.

How can I have nice legible text and keep the size of the file small?
thanks
