Always use XYZReader classes for text input and XYZWriter classes for text output.
java.sun.com has tutorials on Internationalization etc. that I recommend. See also http://oss.software.ibm.com/icu/docs/papers/forms_of_unicode/
Your code takes UTF-8 byte values, mis-casts them to signed then unsigned 16-bit values and re-interprets these mistreated UTF-8 byte values as if they were 16-bit UTF-16 code units.
Let's take this line by line to see what happens:

Here is my code..
while(rsResult.next()) { /*Get the file contents from the value column*/ ipStream = rsResult.getBinaryStream("VALUE");
This is the source of the problem. You read the input as binary instead of as UTF-8 text.
strBuf = new StringBuffer();
while((chunk = ipStream.read())!=-1)
{
byte byChunk = new Integer(chunk).byteValue();
Now you get one byte at a time. In Java, byte is a signed type, so 0x80..0xff are actually negative values: 0x80=-128 .. 0xff=-1.
strBuf.append((char) byChunk);
This widens the signed integer value to 16 bits and then casts it to an unsigned 16-bit unit (Java char is 16 bits wide). 0x80 became negative (-128), was widened to 16 bits and cast to unsigned, which is 0xff80. You append this mistreated value to a StringBuffer which reinterprets it as a UTF-16 code unit.
}
prop.setProperty(rsResult.getString("KEY"), strBuf.toString());
}
