Actually, it is worse. In such a document, to refer to even those Unicode
characters for which there is *not* a character entity reference in HTML,
you have to use mb_encode_numericentity():
$ php -r 'echo mb_encode_numericentity("∎", array(0x0, 0x10000, 0, 0xfffff),
"UTF-8") . PHP_EOL;'
∎
$ locale
LANG=de_CH.UTF-8
LANGUAGE=
LC_CTYPE="de_CH.UTF-8"
LC_NUMERIC="de_CH.UTF-8"
LC_TIME="de_CH.UTF-8"
LC_COLLATE="de_CH.UTF-8"
LC_MONETARY="de_CH.UTF-8"
LC_MESSAGES=en_US.UTF-8
LC_PAPER="de_CH.UTF-8"
LC_NAME="de_CH.UTF-8"
LC_ADDRESS="de_CH.UTF-8"
LC_TELEPHONE="de_CH.UTF-8"
LC_MEASUREMENT="de_CH.UTF-8"
LC_IDENTIFICATION="de_CH.UTF-8"
LC_ALL=
----------

None of this is necessary if you use UTF-8 throughout.
