My output from a 5.0.41 is attached. The 4.1.9 output is the same
except for some wording changes in the encoding warnings. Both
instances have stock configurations right from the MySQL binary tarball,
so when 'table_options={}' runs here, the varchar columns are stored in
the default 'latin1'.
When you're seeing all question marks, is that in the script output or
in the mysql client? I don't think you'd see the cyrillic characters in
the client unless you're using a capable terminal and possibly doing a
'set charset utf8'.
