Re: command fill-paragraph deletes leading Umlauts if line begins with space

[Richard Stallman]

    Couldn't the information about the character syntax which is used in
    multibyte mode also be used in unibyte mode?  (I hope this question is
    not too naive.)

It is naive, but it might make sense in a way.  We could imagine
making the case-conversion commands convert each character to
multibyte and check its syntax.  That way, the syntax of these unibyte
characters could be determined from the current equivalency.

What do people think of that idea?
In particular, Handa, what do you think?
