Just keep them as cstrings and use strcmp. We're only keeping the array 
sorted so that we can binary search it, so we don't need proper 
locale-dependent collation. Note that we already assume that two strings 
('text's) are equal if and only if their binary representations are 
equal (texteq() uses strcmp).
