/*
 * <iconv.h> for the MontaukOS NetSurf port.
 *
 * MontaukOS has no iconv. Rather than port GNU libiconv, this implements the
 * three-function iconv API on top of libparserutils' charset codecs, which are
 * already in the ports sysroot.
 *
 * That is a good fit rather than a bodge: libparserutils decodes a charset to
 * UCS-4 and encodes UCS-4 back out, so iconv() is decode-then-encode through a
 * UCS-4 staging buffer. The supported set is whatever libparserutils supports
 * -- UTF-8, UTF-16, ASCII, ISO-8859-x and the Windows-125x range -- which is
 * exactly the set the HTML parser can handle anyway, so nothing is lost that
 * would otherwise have worked.
 *
 * NetSurf touches iconv only from utils/utf8.c.
 *
 * NOT SUPPORTED: the "//TRANSLIT" and "//IGNORE" suffixes glibc accepts. They
 * are stripped and ignored; conversion uses libparserutils' LOOSE error mode,
 * which substitutes rather than failing.
