solid delta and inverted delta symbol in html

Question

I need to display the following two symbols in an email

1. solid upward delta : something like ▲
2. solid downward delta : ▼

But i cannot use extended-ascii set, because it causes problems in the unix system where my email templates are generated.

Is there any html code, or any other code to accomplish this?

Answer 1

You can try using the unicode values as character entities, as follows:

▲     (for ▲)
▼     (for ▼)

This works for me, but it's worth testing a lot because support in different clients may be quite variable...
