Description

Opening this bug on behalf of Lynh Nguyen.

-------------------------------------------------
The doc says UCASE/LCASE should change case according to
the db locale.

In a turkish db UCASE Should uppercase i to an upper dotted i
and lowercase I to a lower non dotted i, but it changes the
case in the JVM locale. For example ij in the us:

ij> connect 'trdb;create=true;locale=tr_TR';
ij> values UCASE('i');
1
-
I

1 row selected
ij> values LCASE('I');
1
-
i

1 row selected

If I set the jvm locale to turkish I get the turkish
characters.

$ java -Duser.language=tr -Duser.region=TR
org.apache.derby.tools.ij
ij> connect 'jdbc:derby:trdb';
ij> values UCASE('i');
