Is it possible a font has no bold?

hello everyone:
Now i am transfering from flash cs3 to flash cs4, but i found that, some font(such as franklin gothic demi) can’t set to bold directly at flash cs4’s properties panel, but it can be set at flash cs3’s properties panel, this font seems has only normal and italic style.

after seach google, the doc from adobe says “If the selected font does not include a bold or italic style, the style does not appear in the menu. You can select the Faux Bold or Faux Italic styles from the Text menu (Text > Style > Faux Bold or Faux Italic).” – http://help.adobe.com/en_US/Flash/10.0_UsingFlash/WSd60f23110762d6b883b18f10cb1fe1af6-7d29a.html

i was confused, does it possible a font has no bold? if it is true, i can’t change dynamic text to bold?

btw, there are franklin gothic demi and franklin gothic demi italic in my windows/fonts folder, no franklin gothic demi bold and franklin gothic demi bold italic. i have no mac, anyone has gothic demi bold and franklin gothic demi bold italic at your mac fonts folder?
