 /* Depending on which standard the iconv() was implemented with,
    iconv() may or may not use const char ** for the inbuf param.
    If we get this wrong, it's just a warning, so no big deal.

+   This is no longer true with GCC 14, which turns this into an

+   non const by default as that is what the vast majority use.
