Re: [boost] How to handle NULL string for UTF conversion function

4 Dec 2019

      ...
2. Disallow NULL (via assert) for all conversions and require manual
checking. Best usage would then probably be to ditch the temporary and
do `return _wfFoo(s ? wstackstring(s).c_str() : NULL);`
or with some kind of gsl::not_null would be even better?
int fFOO(gsl::not_null s);

But I do not think boost has gsl.
