How to convert UTF-8 <-> UTF16 portable

Question

is there a simple, portable way (win32, linux at least) to convert UTF-16 to UTF-8 and back? Preferably using boost.

Thx for your help, Tobias

Answer 1

Both libiconv and icu can do this.

Answer 2

Well, if this is for academic purposes, you can convert to UTF-32 and then to UTF-8 or UTF-16. Unicode.org has a convenient PDF that contains a table of bit distributions for UTF-32, UTF-16, and UTF-8.
