First of all, this question is unrelated to scripting. You had better asked
it in comp.infosystems.
www.authoring.misc.
I do not know what character GMail actually uses as I have no GMail account
(you should not assume everybody has, so you had better posted a relevant
code snippet of the resulting code). However, GMail must be based on
HTML or XHTML to work in a wide range of Web browsers; the Document
Character Set of these languages is UCS (Universal Character Set)-2 [1]
which translates to the Unicode character set.[2] So you should check
out the Unicode character tables first, particularly the Geometric Shapes
section.[3]
What you need to know regarding J(ava)Script is only that these are
implementations of the ECMAScript language standard.[4] So if you want to
display a UCS-2/Unicode character through scripting, you either must
declare a fitting encoding for the script resource and write the character
as is, or you must use a character escape sequence, such as "\u20AC" for
the Unicode Euro character.
But it could be as well that the "character" you are seeing is in fact only
a small image. Try invoking the context menu for that item and check out
its properties.
