# Twitter Emoji (Twemoji) [](https://travis-ci.org/twitter/twemoji)
A simple library that provides standard Unicode [emoji](http://en.wikipedia.org/wiki/Emoji) support across all platforms.
**Twemoji v12.0** adheres to the [Unicode 12.0 spec](https://unicode.org/versions/Unicode12.0.0/) and supports the [Emoji 12.0 spec](https://www.unicode.org/reports/tr51/tr51-16.html)
The Twemoji library offers support for **3,075** emojis.

## Breaking changes in V2
_TL;DR_: there's no `variant` anymore, all callbacks receive the transformed `iconId` and in some cases the rawText too.
There are a few potentially breaking changes in `twemoji` version 2:
* the `parse` invoked function signature is now `(iconId, options)` instead of `(icon, options, variant)`
* the `attributes` function now receives `(rawText, iconId)` instead of `(icon, variant)`
* the **default** remote protocol is now **https** regardless of whether the current site is _http_ or even _file_
* the **default** PNG icon size is **72** pixels and **there are no other PNG assets** for 16 or 32.
* in order to access latest assets you need to specify *folder* `2/72x72` or `2/svg`.
Everything else is pretty much the same, so if you were using the defaults, all you need to do is to add the version `2/` before the `twemoji.js` file you were using.
## API
Following are all the methods exposed in the `twemoji` namespace.
### twemoji.parse( ... ) V1
This is the main parsing utility and has 3 overloads per parsing type.
There are mainly two kinds of parsing: [string parsing](https://github.com/twitter/twemoji#string-parsing) and [DOM parsing](https://github.com/twitter/twemoji#dom-parsing).
Each of them accepts a callback to generate an image source or an options object with parsing info.
Here is a walkthrough of all parsing possibilities:
##### string parsing (V1)
Given a generic string, replaces all emoji with an `![]()
` tag.
While this can be used to inject emoji via image tags in `innerHTML`, please note that this method does not sanitize the string or prevent malicious code from being executed. As an example, if the text contains a `
