Malformed UTF-8 in load_item_history

[kultur-burgenland]

Steps to reproduce

1. Successfully migrated TeamPass 2.1.27.24 to 2.1.27.36, then to 3.0.0.19 using the official upgrade.php script

2. Getting some "Malformed UTF-8 data" errors now when accessing single items:

        Next error occurred
        Error: Malformed UTF-8 data
   
        Informations:
        - File: items.queries.php
        - Function: load_item_history
   
        Raw answer from server:

3. The item history is empty, everything else gets displayed correctly.

4. Fun fact: If I reload the page, the error does not reoccur and the item including history gets loaded, but a few entries seem to be missing data, e. g. "Tag | Previous value: =>"

5. EDIT: This happens with old (migrated) entries as well as with newly created ones. Changing the default language to english prevents the error message from popping up, but the item history still seems to be missing data ("Tag | Previous value: =>").

Expected behaviour

History should get loaded completely.

Actual behaviour

History does not get loaded completely.
