Characters defined with their unicode codes in HTML won't be imported as symbols, but instead of their codes, for example:

<span>&#26009;</span>
<span>&#36039;</span>

Some of these characters are often used, for example for umlauts (Ä, Ö, Ü) and CJK characters.

The hexadecimal code for Zero Width Space character is split into two parts:
<span>&#x200b;</span> results in Ȁb;
