We have updated the 8.1.0 release notes to mention a fix:

       Some users are having problems loading UTF-8 data into 8.1.X.
       This is because previous versions allowed invalid UTF-8 byte
       sequences to be entered into the database, and this release
       properly accepts only valid UTF-8 sequences. One way to correct a
       dumpfile is to run the command <command>iconv -c -f UTF-8 -t
       UTF-8 -o cleanfile.sql dumpfile.sql</>. The <literal>-c</> option
       removes invalid character sequences. A diff of the two files will
       show the sequences that are invalid. <command>iconv</> reads the
       entire input file into memory so it might be necessary to use
       <application>split</> to break up the dump into multiple smaller
       files for processing.
