Can anyone tell me why the two different data source are displayed as same "자연", while what it contains are different?

I haven't looked into the specific character sequences in-depth, but I suspect the difference is in Normalization Forms. Specifically, form C vs. D.

http://unicode.org/reports/tr15/

The idea is that the same character can be obtained from a single code point or by several combining code points.

In Cocoa, see -precomposedStringWithCanonicalMapping and - decomposedStringWithCanonicalMapping.
