U+2047 double question mark collation

[Vadim Godunko]

Hi,

I have a problem with creating collation key for U+2047 (double question mark).

Explicit collation keys for this symbol is absent in allkeys.txt.

In UnicodeData.txt this symbol have compatibility decomposition map.

2047: ... :<compat> 003F 003F: ...

Based on this and as defined in UTR #10 Unicode Collation Algoriphm this symbol must have these collation keys:

003F [*024E.0020.0004]
003F [*024E.0020.0004]

But in CollationTest_NON_IGNORABLE.txt assumes that symbol have implicit collation key [FBC0.0020.0002] [A047.0000.0000].

What is incorrect?
