There is nothing special about importing OpenType fonts: use the File >
Open command to open files with .ttf extension (which mean TrueType-
flavoured OpenType font) or .otf extension (CFF-flavoured version of the
format).
To read OpenType features make sure that this option is active in the
Tools > Options > OpenType panel:
The following option:
Will import kerning defined in the “kern” positioning feature into a font
pair kerning table. We recommended you have this feature active when you
import the OpenType font.
FontLab will try to decompile OpenType features defined in the GPOS and
GSUB tables. It can read almost all substitution features and single and
pair positioning features. FontLab does not support Mark attachment
features.
If a GDEF table is defined in the font, FontLab will read information about
anchors, glyph types and caret positions from it.
