Description:
MySQL cannot convert "Division Sign" to 'eucjpms' from the other character-set.

Division Sign
  Unicode(ucs2,utf8)    U+0000F7
  EUC(ujis,eucjpms)     0xA1E0
  Shift-JIS(sjis,cp932) 0x8180

#The following is "Client -> Table" case.
#This probrem is seen even at "Table -> Client" case.

How to repeat:
<<<eucjpms (probrem)>>>

create table test_eucjpms ( str varchar(10) ) default character set eucjpms;
insert into test_eucjpms values ( _ucs2 0x00F7 );
insert into test_eucjpms values ( _eucjpms 0xA1E0 );
insert into test_eucjpms values ( _ujis 0xA1E0 );
insert into test_eucjpms values ( _sjis 0x8180 );
insert into test_eucjpms values ( _cp932 0x8180 );

mysql> select hex(str) from test_eucjpms;
+----------+
| hex(str) |
+----------+
|          |
| A1E0     |
|          |
|          |
|          |
+----------+

....not converted from the other character-set!

<<<ujis (correct case)>>>

create table test_ujis ( str varchar(10) ) default character set ujis;
insert into test_ujis values ( _ucs2 0x00F7 );
insert into test_ujis values ( _eucjpms 0xA1E0 );
insert into test_ujis values ( _ujis 0xA1E0 );
insert into test_ujis values ( _sjis 0x8180 );
insert into test_ujis values ( _cp932 0x8180 );

mysql> select hex(str) from test_ujis;
+----------+
| hex(str) |
+----------+
| A1E0     |
| A1E0     |
| A1E0     |
| A1E0     |
| A1E0     |
+----------+

....converted correctly even from the other character-set.
