Question

http://www.sqlfiddle.com/#!2/82f65/1

I tried this:

create table x(y varchar(100) character set utf8);

insert into x(y) values('爱');

But the chinese character doesn’t appear:

select y from x;

Output:

Y
?

I’m the author of sqlfiddle.com. The problem was that I didn’t have my connection string and default database encoding for mysql setup to properly handle UTF8. I have fixed this now, but because the fiddle you posted is still using the obsolete settings, you’ll have to see it working here on my slightly-modified version of your fiddle:

Your link might start working eventually, it just needs to clear out of the running memory and be reset. After no one hits it for a while it should be harvested and then ready to be built back up cleanly. Thanks!

FYI, the changes I had to make to get it to work were found here: http://www.compoundtheory.com/?action=displayPost&ID=421

The relavent bits where adding this to my connection string from java:
useUnicode=true&characterEncoding=UTF-8

And adding this to my create database statement:

create database my_new_database default CHARACTER SET = utf8 default COLLATE = utf8_general_ci;
