[2.2.0] Checkmk Werk 14860 created: EC: improve handling of non-UTF-8 characters in messages

Title: EC: improve handling of non-UTF-8 characters in messages Class: fix Compatible: compat Component: ec Date: 1708674008 Edition: cee Level: 1 Version: 2.2.0p23 Previously, the Event Console would show an error such as "UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte" when trying to process a message that contained non-UTF-8 characters. With this werk, the EC no longer crashes. Any non-UTF-8 sequence of bytes is replaced with U+FFFD, the standard Unicode replacement character for an unrecognized character.
