Just to give an example ...
In some loaders we have (the example is taken from Sanskrit):
% Set \lccode for ZWNJ and ZWJ.
% Set \lccode for KANNADA SIGN JIHVAMULIYA and KANNADA SIGN UPADHMANIYA.
Alternatively you can also write characters instead of hexadecimal
numbers. For example, for German you do need:
but it probably still hyphenates somehow without those. If you want to
hyphenate russian, you need to provide \lccode command for every
letter of Russian alphabet, both for uppercase and lowercase letters
(they need to point to lowercase).
This should be fixed in format one day though, but if you want to use
it now, this is what you need to do ...
