%D The codes are stored in the format, so we don't need to reinitialize
%D them (unless of course we have adapted the table). It is on the agenda
%D to do this with \type {tex.lccode} cum suis once they're available.

%D There may be a problem with the turkisch patterns. By now it's taken care of in
%D ctxtools (thanks to Mojca). There seems to be a bug in the patterns (^^11 refers
%D to a double quote but it should be ^^19 since the original is in ec encoding).
