Software applications which do not support OpenType layout features (check which software does support OTF features) can only display the default forms of letters and numbers. Typotheque fonts designed for small sizes usually use Old Style figures, while fonts designed for headlines use Lining figures.
Older versions of Microsoft Word use only the default numeral forms. Newer applications such as the Adobe Creative Suite programs, or Microsoft Word 2010 can control the OpenType features of the fonts. In Word 2010ʼs Home tab, click the Font Dialog Box Launcher, then click the Advanced tab, where you can select Ligatures, Number forms, Stylistic sets or Contextual Alternates.
Please note that Word can’t access Small Caps. Read more about OpenType features in Office 2010.
