convert raw bytes to Unicode strings

Does standard C++ have any methods to do this? I'd like to convert raw
bytes to utf-8. Thanks for any tips.

string to gain a better understanding of this difference.

But when you take a string containing characters, and you encode it
into a sequence of UTF-8 bytes, you don't get a string, but a sequence
of bytes.

What is the difference between these bytes and your "raw" bytes?

Do you know what UTF-8 is? (read at least wikipedia article about it).


Anyways, there's no standard C++ function to do what you want. You
could use an external library like libiconv, or just write the utf-8
encoding/decoding algorithm in C++ yourself.

There is no separate "concept of a char" from that, at least in C++.

C++ has no specific provisions for UTF-8. There is the class 'codecvt'
(actually a class template), that the Standard says "is for use when
converting from one codeset to another". Perhaps you should look into
that...
