Python 2.2.1 (#1, Apr 10 2002, 19:08:12)
[GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-98)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> "test+AEA-qa21.com+ADs- dig+AEA-qa21.com".decode("utf-7")
u'test at qa21.com; dig at qa21.com'

And if "I'm working on C/C++ platform" means you need the
algorithms callable from C, then use the function
PyUnicode_DecodeUTF7().

If "I'm working on C/C++ platform" means your program has nothing
to do with Python, this is really the wrong newsgroup, but you
could take a look at PyUnicode_DecodeUTF7() in the Python source,
(in the file Objects/unicodeobject.c, viewable online at
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/python/python/dist/src/Objects/unicodeobject.c?rev=HEAD&content-type=text/vnd.viewcvs-markup
) and copy the algorithm from there.

Hope that helps,
