16%D After a bit of experimenting we reached a clean state where \UTF\ 8, 16 and 32
17%D were supported as well as collapsing (combining sequences). Writing the code was
18%D a relaxed experience, not in the last place because it was accompanied by
19%D listening to those nice Vienna Teng cd's (who decided that making music was more
20%D fun than programming, but then, she may not know \TEX\ and \LUA).

29%D We enable collapsing (combining characters) by default, but since the source
30%D files are rather simple, we postpone the initialization till runtime.
