After this step, the code iterates and registers all ICU aliases for ISO-8859-8, which includes ISO-8859-8-I (see <http://demo.icu-project.org/icu-bin/convexp?s=IANA&s=MIME>).

… so textEncodingNameMap->get("ISO-8859-8-I") will return "ISO-8859-8".

> c) textEncodingNameMap->add("ISO-8859-8-I", "ISO-8859-8-I")
