--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
But how will you know what MB_LEN_MAX the different implementations use?
And does it really have to be a single character, not a string?

At least in glibc in the included locales there are just 3 decimal_point forms,
"<U002C>", "<U002E>" and "<U066B>".  But perhaps you should see if localedef
allows you to define something containing multiple characters (or a single one
from surrogate pair etc.).  Would be also interesting to see if zero length
radix character will get through.
