I can repeat more-or-less what you saw. It appears to be a problem in Qt's HTML renderer. The HTML generated by calibre is fine.

Example: a composite that produces one character as output:

Code:

program: '✏️'

The resulting HTML

Code:

<div id="_composite" class="comments"><p class="description">✏️</p></div>

An online HTML renderer gives me this:
Attachment 212932

The result in book details is this. Note that I see a pencil, just not the one the character specifies:
Attachment 212930

If I turn on the field header then I get this:
Attachment 212931

Clearly Qt's renderer is misbehaving. I don't know why, but there are now two workarounds:

The one you used, a zero-width space.
Turn on the header.
