Time for change. The inputenc package makes use of active characters
and multibyte characters come in pieces. If your macro contains
\futurelet\somechar\dosomething then \somechar may contain a part of a
character. another example, suppose that you redefine \chapter so that
it changes the first character into an initial by:

  % code for putting #1 as an initial

Now #1 may contain just a part of a character and using this part will
cause an error. That's why I cannot use inputenc even with Czech, I
need above mentioned constructs in my LaTeX macros and the same macro
must work both with accented and non-accented characters. Moreover,
non-accented characters can be compared by \if, multibyte characters
and active characters cannot.
