Description:
------------
When I try to convert unicode-text into ascii via  "transliterator_transliterate()" it converts "ℌ" into "x" instead of "H".

- demo: https://3v4l.org/DVIs7

- sample-unicode (for more tests?): https://github.com/voku/portable-utf8/blob/master/tests/fixtures/sample-unicode-chart.txt

Test script:
---------------
$str = 'ℌ';

$str = transliterator_transliterate('NFD; [:Nonspacing Mark:] Remove; NFC; Any-Latin; Latin-ASCII;', $str);

var_dump($str);

Expected result:
----------------
H

Actual result:
--------------
x
