[sqlite] Odd results with ICU extensions?

[Philip Warner]

I've been using SqlCipher (built locally with ICU extensions) and can do the 
following:

sqlite> select icu_load_collation('[][][]','q');
sqlite> select * from foo order by f1 collate q;

Which worries me.

I assume this is an Sqlite+ICU problem.

Does anyone have any insights into what is going on here? I had expected an 
error message.
