I was running version 2.38, so I upgraded to 2.39, but I'm still
getting the same results. The doc.xml file for the words above has
W�~C¶rtern f�~C¼r, and when my browser displays it, it still looks like
Wörtern fÃ1⁄4r. It almost looks like Greenstone is converting to
UTF-8 twice--at any rate, I end up with four bytes apiece for an
o-umlaut and a u-umlaut, when their UTF-8 encoding should be two bytes, right? Interestingly, the very first character with an umlaut in this file appears in doc.xml as künstliche, which ends up
displaying properly (View Source shows künstliche), but of course I can't search on it (the original file has künstliche and
für, but the two u-umlauts are rendered differently!). I've tried viewing the files on a variety of browsers on different platforms
(Windows & Mac), all set to use UTF-8 encoding, all with the same
results.

It looks to me like the doc.xml file is the problem. You said to try
explicitly telling the plugin the encoding of the files. Which plugin? The file is at http://alpha.reltech.org:8091 select PBP-test, title
a-z, 62... (the first item).
