Description Mathias Bynens 2012-08-05 00:46:34 PDT 
Password fields display two replacement characters for a single supplementary Unicode symbol.

Test case here: data:text/html;charset=utf-8,<input%20type=password%20value=&%23x1D306;>

As you can see, two replacement characters are shown instead of one. What’s worse is you can delete each individual surrogate separately.
