What would be the Unicode character for big bullet in the middle of the character?

Question

http://www.unicode.org is the place to look for symbol names.

● BLACK CIRCLE        25CF
⚫ MEDIUM BLACK CIRCLE 26AB
⬤ BLACK LARGE CIRCLE  2B24

or even:

🌑 NEW MOON SYMBOL   1F311

Good luck finding a font that supports them all. Only one shows up in Windows 7 with Chrome.

Here's a full list of black dotlike characters from Unicode:

number	character	HTML entity	Description
U+00B7	·	·	Middle Dot
U+25CF	●	●	Black Circle
U+23FA	⏺	⏺	Black Circle for Record Emoji
U+26AB	⚫	⚫	Medium Black Circle Emoji
U+2B24	⬤	⬤	Black Large Circle
U+29ED	⧭	⧭	Black Circle with Down Arrow
U+1F784	🞄	🞄	Black Slightly Small Circle
U+2022	•	•	Black Small Circle
U+2219	∙	∙	Bullet Operator
U+22C5	⋅	⋅	Dot Operator
U+1F311	🌑	🌑	New Moon Symbol Emoji
U+30FB	・	・	Katakana Middle Dot

You can use a span with 50% border radius.

 .mydot{
     background: rgb(66, 183, 42);
     border-radius: 50%;
     display: inline-block;
     height: 20px;
     margin-left: 4px;
     margin-right: 4px;
     width: 20px;
}    

<span class="mydot"></span>

You can search for “bullet” when using e.g. BabelPad (which has a Character Map where you can search by character name), but you will hardly find anything larger than U+2022 BULLET (though the size depends on font). Searching for “circle” finds many characters, too many, as the string appears in so many names. The largest simple circle is probably U+25CF BLACK CIRCLE “●”. If it’s too large U+26AB MEDIUM BLACK CIRCLE “⚫” might be suitable.

Beware that few fonts contain these characters.

A new problem has emerged with characters like MEDIUM BLACK CIRCLE, a problem that you may well see above. As noted in a comment, this character may look (much) larger than BLACK CIRCLE. The reason is that it may be rendered in “emoji style” as opposite to “text style”; this is explicitly mentioned in an annotation for the character in the Unicode Standard. In principle, you can use a Variation Selector (VS15 or VS16) character after the character to specify the style, but in practice it probably does not work. An explicit selection of font, e.g. Segoe UI Symbol (instead of Segoe UI Emoji) tends to be more successful.

If you are on Windows (Any Version)

Go to start -> then search character map

that's where you will find 1000s of characters with their Unicode in the advance view you can get more options that you can use for different encoding symbols.
