Surrogate are not supported by Eclipse.
See Bug 65899 and Bug 69814

same text encoded as java literal:
"\uD840\uDC00\uD87E\uDE1D\uD840\uDC00\uD840\uDC01\uD840\uDC02\uD840\uDC03\uD840\uDC04\uD869\uDED4\uD869\uDED5\uD869\uDED6\uD840\uDC0B\uD868\uDD90\uD869\uDEB2"

On windows, two backspaces are needed to delete one surrogate pair (see bug 69814).

I decide to use bug 65899 as generic request to support surrogetes on linux-gtk.
closing this as duplicate.
