Re: GNU Emacs 22.0.50 fails to find ä in different ISO Latin encodings

[Richard Stallman]

    A while ago, I proposed to change isearch so that it
    translates characters by translation-table-for-input to
    solve such a problem, but there raised an objection that
    read-char should do that translation.  RMS asked to check if
    such a change to read-char is surely safe or not, but as
    such a check is very difficult and time-consuiming, no one
    took on the job.

    So, this problem is still unfixed.

    I again propose to change isearch.

Yes, let's do it that way.  Could you do it now?

That is true, so we already have our long-term solution.
For now, fixing isearch is sufficient.
