Is the same "C" locale has. We only want consistency, see 38368.

I suppose so, because we have a comment in the code (resulting from feedback me
and / or Benjamin got from glibc people clearly saying that '\0' implies no
grouping. We always worked under this hypothesis.


 locales, e.g. bg_BG, that specify empty thousands_sep, yet have
> grouping 3;3.  For empty thousands_sep glibc just forces no grouping:

>               || (! wide && *thousands_sep == '\0'))
>             grouping = NULL;

Ok...

This is just a C++ standard issue, unfortunately...
