Custom Font - letters missing

Hi all,

I am sure there is already a post for this but I just still can't find the right answer. Each of the business in my group have their own branding guidelines, including fonts. When I create a Storyline, I usually use the font based on their branding guideline, which sometimes are not the windows system default fonts.

Some users cannot see the exact font that I selected and letter 'f' is missing. I thought fonts are actually embedded onto the Storyline and not depending on whether the user have that font installed onto their device?? If fonts are not embedding, does it mean I should always use a common windows  font, such as Times New Roman?

Thanks

Anthony
