Accessing OpenType font features in LA<\/sup>TE<\/sub>X<\/span><\/h2>\n

\"OpenType<\/a>Mainstream typography websites discussing OpenType support in design and typesetting applications (1<\/a>–2<\/a>) seem to be largely unaware of the amazing work<\/a> done by the creators of the X\u018e<\/sub>TE<\/sub>X<\/span> typesetting system and of its high-level interface to OpenType features (the fontspec<\/a> package). To bridge this gap I put together a table with a list of font features currently supported in X\u018e<\/sub>TE<\/sub>X<\/span>, based on version 2.0<\/tt> of fontspec. TE<\/sub>X<\/span> distributions such as X\u018e<\/sub>TE<\/sub>X<\/span> allow you to make the most of the advanced typographic features<\/a> available with expert fonts via a simple user interface.<\/p>\n

Activating font features with fontspec<\/h4>\n

Specific OpenType features can be activated globally, by declaring them in the document defaults:<\/p>\n

\n
\\setmainfont[<font features>]{<font name>}<\/pre>\n<\/div>\n
or locally in the text, only when needed:<\/p>\n
\n
\\addfontfeature{<font features>}<\/pre>\n<\/div>\n
 <\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
