[Koha] Framework ACQ causes mutilated special characters

[Michael Kuhn]

Hi

We have tested the following with Koha 18.11.03 and 20.11.00, both on 
Debian 9.

We are using framework ACQ (downloaded from 
https://wiki.koha-community.org/wiki/MARC_frameworks ) and have 
activated Koha system preference "UseACQFrameworkForBiblioRecords".

In Koha menu "Acquisitions > Vendor > New basket > Add order to basket: 
 From a new (empty) record" we can see the MARC fields from framework 
ACQ. Now if we enter for example "Mäuse und Vögel" in MARC 245 $a an 
order is created which shows the correct title "Mäuse und Vögel" in 
column "Order".

But when clicking this title to open the cataloging view we see the 
title is actually mutilated to "Mũse und Vg̲el". Or in other words, 
Unicode strings "äu" (octal 303 244 165) and "ög" (octal 303 266 147) 
have become octal 165 314 203 and 147 314 262.

Can anyone please confirm this? Is there a solution for this problem or 
should we open a bug report for this?

Many thanks in advance.

Best wishes: Michael
