I have also the problem to show CJK characters if LANG and LC_ALL are set to

The following sample can reproduce this:

using System;
using System.Windows.Forms;

class MainClass
        public static void Main(string[] args)
                string text ="\u30C0";
                Form form = new Form();
                form.Text = text;
                Label label = new Label();
                label.Text = text;

When sample is running it shows only squares where CJK characters should be.
If I set LANG to ja_JP.utf8, then the characters are shown correctly.
