I'm curious about something. Do you have a realistic expectation that
your code might need to work under an implementation with CHAR_BIT > 8?
Do you have such a target system in mind?
C++ with the assumption that CHAR_BIT==8 is realistically at least 99%
as portable as C++ without that assumption -- and far more portable than
C++ with the assumption that Qt is available.
