Need to display multiple font in single text field

Hi All,
I am working on a flash application which would have a text field displaying multiple fonts in it. I have embedded the fonts and have added it to the library.I can view them in my computer whereas when viewed in another computer without the font used, display is different.

Add a <font face=“library font one”>registered mark </font>directly (®) or <font face=“library font two”> with a Unicode escape sequence</font>

After the fonts are embedded size of the swf does go up. What could be wrong?
