inserted symbol shows up different when doc emailed to another

[Guest]

I have typed a word document that included an inserted symbol of a check box.
When I email the document to a colleague, on her computer the check box
appears as a circle with a 6 inside. It's like her machine is not
recognising the same symbol. Our I/T person does not know what the problem
is. Can anybody help??
thank you

It means you've used a font that isn't on your recipient's computer, so
their copy of Word has substituted another. 6 in a circle is appears in some
of the WingDings fonts.

One looks askance at your IT person's response.
