I don't believe this is actually an 8.3 server. In 8.1 or later that
encoding would be referred to as "UTF8"; also, 8.1 and later would show
all bytes of the complained-of character not just the first one.

8.0 and before only support 16-bit Unicode code points (ie, 3-byte
utf8 sequences). We have support for 4-byte sequences in 8.1 and
later. Also, there were some fixes in this area in Jan 2007, so
whichever branch you use, make sure you get a minor release that's
newer than that.
