When you have a font that contains feature definitions and you want them
to be exported to an OpenType font file, the first thing you need to do is to
compile and test your features using the tools in the OpenType panel.
If feature definitions contain errors, they will not be exported and you will
get a plain TrueType font file without any features. If you are exporting a
CFF-flavoured OpenType font and the feature definitions contain an error
the font will not be exported at all.
When you know that there are no errors in the features and the features
work as expected, you need to check the OpenType export options in the
Tools > Options > OpenType dialog box:
Export OpenType Tables
OpenType features will be exported only when this option is active.
Export VOLT data
If this option is switched on, FontLab will try to export feature definition
data in a format supported by Microsoft VOLT (Visual OpenType Layout
Tool). Not all features can be exported. Refer to the next section for more
information.
