Unicode FAQ disagrees (http://unicode.org/faq/utf_bom.html):

"Q: How about using UTF-32 interfaces in my APIs?

A: Except in some environments that store text as UTF-32 in 
memory, most Unicode APIs are using UTF-16. With UTF-16 APIs  the 
low level indexing is at the storage or code unit level, with 
higher-level mechanisms for graphemes or words specifying their 
boundaries in terms of the code units. This provides efficiency 
at the low levels, and the required functionality at the high 
levels."
