How to handle string and wstring in one project

Question

I am writing code that uses string and the code needs to be compiled alongside other projects. Some of these projects are using Unicode and some others using multi byte string.

How can write my code in a way that it can be compiled in both configuration?

For example I know that TCHAR is a macro that expand to suitable char based on configuration. Is there any similar things for string/wstring?

What is the best practise on using string/wstring when portability is important?

Answer 1

You should use std::wstring to store your strings, then convert the strings to what the libraries that you are using is requesting as needed.
