Perhaps you mean UTF-32 ?

Now you've got me curious, by bringing up surrogate pairs.  Do you know 
whether a narrow build (say 3.2) really works as UTF16, so when you 
encode a surrogate pair (4 bytes) to UTF-8, it encodes a single Unicode 
character into a single UTF-8 sequence (prob.  4 bytes long) ?
