# Emoji for Java

Replaces emoticons such as `:-)` with their corresponding Unicode emoji.

This allows for a graphical representation of the symbols, e.g. through bitmap graphics or emoji fonts.

## Installation

 * Copy `Emoji.java` to your project

## Usage

````
String myString;

myString = "Smiling face :-) is shown";
// Smiling face :-) is shown

myString = Emoji.replaceInText(myString);
// Smiling face <?php echo utf8(0x1F60A); ?> is shown
````
