But it is the creating of searchable document that I have in mind. It is
the current situation that gives non searchable document.

If you run the following document with pdfLaTeX and then search for "ss"
you will get no hit. But if you search for ß the \char223 and the
uppercase ß (the both "SS") are found:



And this is the correct result. The word is schließen and not
schliessen! So the above document has the correct visual look (the two
SS) and searching works. Replacing \char223 (the uppercase version of
the ß) by two distinct S  may look similar, but it changes the
orthography and so the search now fails.
