Usage

1. Add a new contenteditable div to your HTML that serves as the input:

2. Import InputAbbreviationRewriter from this package and create a new InputAbbreviationRewriter for #unicode-input
3. Make sure to call InputAbbreviationRewriter.resetAbbreviations whenever setting the text of #unicode-input programmatically, as the InputAbbreviationRewriter only triggers on actual user input
4. Add white-space: -moz-pre-space to #unicode-input, otherwise there's an error with multiple spaces on Firefox.
5. Style #unicode-input to your liking

This component only supports single-line input and no rich text styling other than the abbreviation highlighting.
