Hello List,

This is a general question regarding UTF-8/UTF-16/UTF-32 design 
implementation. I would appreciate and comments to this design.

Create classes of utf8/utf16/utf32 who has a public base of 
std::vector<char>.

Make all the std::vector<char> methods private (proxy like approach 
without the pointer) to avoid calling the public base directly from code 
without down casting (And the signatures should be diffrent anyway, see 
below).

Re-implement common vector functions as public methods for unicode 
manipulation from the derived classes of utf* using boost::uint32_t as 
the code point type.

Allow passing of down casted utf* classes into functions that will 
handle std::vector<char> types (boost::asio). This should also allow 
direct manipulation of the underlying data.

Good/Bad/Terrible Idea?

These classes should only be for the manipulation of code points and not 
for the extraction of characters (combining character classes etc).
