Kerning
#######
***********
Description
***********
Kerning groups must begin with standard prefixes. The prefix for groups intended for use in the first side of a kerning pair is ``public.kern1.``. The prefix for groups intended for use in the second side of a kerning pair is ``public.kern2.``. One or more characters must follow the prefix.
Kerning groups must strictly adhere to the following rules:
#. Kerning group names must begin with the appropriate prefix.
#. Only kerning groups are allowed to use the kerning group prefixes in their names.
#. Kerning groups are not required to appear in the kerning pairs.
#. Glyphs must not appear in more than one kerning group per side.
These rules come from the `Unified Font Object <http://unifiedfontobject.org/versions/ufo3/groups.plist/>`_, more information on implementation details for application developers can be found there.
