[bug-gnu-libiconv] libiconv on FreeBSD 10 don't convert utf-8 -> wchar_t

[kora]

I try to port my software written in C++ to FreeBSD 10.2.
I need to convert strings
"utf-8 -> wchar_t" respectively
"wchar_t -> utf-8"

Using the "libiconv" converter  libraryit returns Errno 86
if the string contains a non ANSII character.

Has anybody a hint or solution for that problem ?


Cheers
