What is a FEA file?
An FEA file is a data file commonly used in .UFO files to store font data. It contains Adobe Font Development Kit for OpenType (AFDKO) feature definitions, which may include language coverage, ligature, kerning, contour, and cursive information. FEA files are saved in plain text.
FEA files are typically found in UFO files, along with .PLIST, .GLIF, and .PNG files. FEA files typically are not removed from UFO files and are accessed when a program, such as FontForge, RoboFont, or Glyphs, opens the UFO file. However, since FEA files are saved in plain text, they can be opened by a plain text editor.
