Generating and using custom GNFUL ↩
GNUFL, Glyph Namer Formatted Unicode List is a glyph name - unicode generator. You can specify your custom GNFUL in the Preferences > Font Overview.
The glyphNameFormatter module is embedded in RoboFont, so you can access it with Python. The following example loads a custom GNFUL and generates a list with a custom separator.
from glyphNameFormatter.exporters.exportFlatLists import generateFlat
gnfulPath = "path/to/your/gnful.txt"
generateFlat(gnfulPath, scriptSeparator=":")
