Are you characters being escaped before being stored?
\u<character-code>?

You know, now I'm sure that the chars are getting stored as '?' as well.
I tried the test you suggested again, but with a small modification. I
typed:
SELECT IF(networkname='?', 1, 0) from networktable;
and it returned 1. Because I used '?' instead of the chinese char and it
matched, then obviously the stored character is a '?'. So my conclusion
is the same as James Huang's; the problem happens when the string is
stored. But no solution yet, though.

If you can type the character into the keyboard try this.
SELECT IF(col1=<chinese-character>, 1, 0)
Else try this from a java program
if (rset.getString(col1).equals(<chinese-character>))
{
System.out.println("match");
}
else
{System.out.println("invalid");
}

Yes, my display can handle the Chinese characters. I have also changed
the application font of MySQL Control Center to SimSun, which supports
all the Chinese characters I am using. When I type the characters in
MySQL Control Center, I see the Chinese characters. I edit a varchar
field in an existing record, I type the Chinese content, hit enter, save
the table, and I still see the Chinese characters. When I requery the
table, the Chinese characters have become question marks.
As for verifying whether the correct Unicode is being stored, how do I
do that? All I can see once I requery are the question marks. I don't
know whether the Unicode is being stored as question marks, or whether
it is stored correctly and is getting converted to question marks when
the stored data is retrieved.

Can you display properly handle the Chinese characters? I would try to
verify that the correct unicode code is being stored.

I saw the same problem with 5.0 alpha and Java/JDBC. The text was
Chinese
characters in Java; the tables were created with default character set
UTF8.
Seems only questions marks are stored.
Wondering if far-east characters in UTF8 are support by MySQL's UTF8
support?
