I don't know. And I can't answer your question since I don't know
where in Unicode this range is. With some more input I might be able
to give better answers.
In GNU, Carbon, and Cocoa Emacsen and all other flavours you have the
chance to *enter* every Unicode character. When it gets displayed as
a box, then it's still valid, there is just no glyph available from
some font to display it. The Mac OS X grep obviously is able to
handle the whole Unicode range, at least the BMP (Basic Multilingual
Plane). I have no other test cases to test any other plane. The
mechanism to enter this characters is, for example, C-q <some octal
code><SPC|RET|cursor>, i.e. you press C-q and then enter the octal
code of that character. I think this input sequence ends when it
reaches its natural limit of 177777 for the BMP. If you have to enter
only a few digits, then you'll need to finish this "mode," which is
every non-digit. It's also possible to make this mechanism accept
numbers to the base of 16, so the value form the Unicode notation U
+ABCD can be used.
