[Koha] OPAC searches fail with ICU indexing enabled

Dear list,

We're running Koha 3.20.04 on Ubuntu 14.04, and recently enabled
ICU indexing as per the instructions on the wiki

Most searches work fine, but queries for certain Greek characters in OPAC
(for example "[χ.ό.]"), return the following message:

:8: parser error : Input is not proper UTF-8, indicate encoding !
Bytes: 0xCF 0x3C 0x2F 0x74 ος Τιμόθεον Α΄-προς
Τιμόθεον Β΄-προς Τίτον-π ^

If I use the command-line zebra client to perform the same search,
I get 335 hits:

$ yaz-client -c /etc/koha/zebradb/ccl.properties
Sent initrequest.

So, it looks as if Zebra can actually perform the search but somehow
the results cannot be displayed in OPAC.

Does anyone have any clues as to why this is happening?

Kind regards,
