Check box symbol

How do I enter the checkbox symbol in an email, using eM Client? It seens non of the ascii or unicode work as recommended by google.
I can go to insert symbol, unicode, but get a different symbol.
Any suggestions please? Thanks, Gerard

It is dependent on the font you are using. The default font used in eM Client, Segoe UI, does not have a checkbox character.

So you will need to use a font that does for that character, like Wingdings, for example.

Or use an emoticon instead.
