\writestatus{loading}{ConTeXt Character Support / Unicode UTF}

%D After a bit of experimenting we reached a clean state where \UTF\
%D 8, 16 and 32 were supported as well as collapsing (combining
%D sequences). Writing the code was a relaxed experience, not in the
%D last place because it was accompanied by listening to those nice
%D Vienna Teng cd's (who decided that making music was more fun than
%D programming, but then, she may not know \TEX\ and \LUA).

%D We enable collapsing (combining characters) by default, but
%D since the source files are rather simple, we postpone the
%D initialization till runtime.
