It is U+9F44. Why don't you select U+9FBB ?
And another group starting U+F900 may be used in CJK.
Making index of chinese and sort by it, the highest char is Char(65528). This is U+FFF8.
This is highest in English index too, so may be fit for your use ?
Many thanks. Char ( 65528 ) works fine and solved the problem
