I already tried to propose a patch going in the direction you
indicate, but the replies were not very positive...

> NetBSD has iconv support, essentially the same as in glibc, with one
> crucial difference that messes up GDB.

> In gdb_wchar.h, INTERMEDIATE_ENCODING is hardcoded as "wchar_t" and in
> charset.c iconv_open() is called with INTERMEDIATE_ENCODING as the "to"
> format.

> As it happens, the NetBSD implementation of iconf does not list
