I have also encountered this issue. Mark, per your recommendation, I have attempted to modify BitstreamReader.
I did not see a place to set encoding apart from the mime type.
this.bitstreamMimeType = bitstream.getFormat().getMIMEType();
if (bitstreamMimeType.equals("text/html")) {
bitstreamMimeType = "text/html; charset=UTF-8";
}
this.bitstreamName = bitstream.getName();
Based on a couple quick tests, this looks promising.
Is this what you were recommending?

worked just fine, but in DSpace 3.1, the encoding for ONLY the bitstreams
was coming out as ISO-8859 instead. After much searching, I finally found a
workaround which involved changing a value in the web.xml file, as follows:

substituted the Spring one (which is already included by default). So I had
to change only these lines, and my encoding problem was resolved. This
tells me there might be a problem in the DSpace encoding filter ... ?
Thank you. Interesting. If this works well, then at the least we
could just use Spring's filter and stop maintaining our own.
I'm thinking that our filter as written could never have done what you
expect, and the effect was produced elsewhere. Our filter only sets
the request's encoding. Spring's filter is documented to also set the
response's encoding when forceEncoding=true. Perhaps BitstreamReader
should just set the encoding on the response?
