+%D As not all fonts, even the expensive ones, support some of the most frequent
+%D unicode signs used in ISO~9 there are fallbacks for the transliterations of
+%D the weak and hard sign: \type{iso9_ocs_hack}, which is essentially
+%D \type{iso9_ocs}, and \type{ru_old_jer_hack}, which is essentially
+%D \type{ru_old}. These two transliterate {\em ь} and {\em ъ} (both upper and
+%D lower case) to the more common, but non-ISO characters {\em '} and {\em ''}
+%D respectively.
%D Possible values for \type{hyphenate} are all valid \CONTEXT\ language code, for an
%D overview see \type{http://wiki.contextgarden.net/Language_Codes}.
%D In praxi you may want to choose either Czech (the default) or Slovak
