Use "C-u C-x =" on the character and look at "preferred charset"
property.

I think it can: see `org-html-coding-system'. It may be wiser to avoid
these symbols altogether.

Any additional package needed must be added to
`org-latex-default-packages-alist', which means that the package will be
loaded in every LaTeX export. So, this is clearly not OK for packages
like "kpfonts".
As a rule of thumb, I think we should avoid requiring new packages for
org-entities.

Sounds good.

Why is there a space in UTF-8 code?

This one is LaTeX specific, it may be more appropriate in
`org-entities-user'.

Ditto. Also, the LaTeX code looks wrong.

Didn't you forget a "\not" in LaTeX entry?

Is is really needed? There are already two entities producing the same
code.

Ditto.
> ("Leftrightarrow" "\\Leftrightarrow" t "⇔" "<=>" "<=>" "⇔")
> + ("iff" "\\iff" t "⇔" "<=>" "<=>" "⇔")
Ditto.
