Oh dear! The forum software cut my message off at the first complicated character!

The rest of what I intended to say:

Instead of the emoji for "Deciduous tree" (tree emoji here) what I end up with is the character U+FFF3 (something from the unicode private use area).

The same thing happens if I enter the decimal equivalent:

& # 1 2 7 7 9 5 ;

However, should I enter that text inside an HTML attribute (e.g. in the title attribute of an <img> tag), that seems to work and the rendered HTML includes the deciduous tree emoji.

Entering in two numeric character entities for the UTF-16 surrogate pair also fails to work, but entering the emoji directly does.
