i've already asked this on the adobe forums but nobody seems to have had this problem in the past, so i'm gonna try here:
situation:
i have a pdf-file (http://www.groneick.de/martinsmarkt.pdf) in which i want to search for an occasion of "außergewöhnlich"
C:\Users\username>cd c:\
c:\>"c:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe" /A search=außergewöhnlich c:\martinsmarkt.pdf
given the case the pdf-file is at c:\
what happens is, the adobe reader software is searching for occurences of "auergewhnlich".
i have found that there seems to not be any difference between a->ä / ö->o / ü->u, but what about the "ß"? (saying i could search for "ubernaturlich" and it would find "übernatürlich" aswell)
using "ss" for "ß" doesnt do the job, neither does "s" instead of "ß"
i am really really stuck on this one ... so i would be very glad if somebody could point me towards a solution.
here is the thread inside the adobe forums:
even though it's not the root of the problem i have now "solved" the problem by telling the hosting c#-program to fill the search-form the hard way by controlling the up-popping adobe reader
