 # Unicode::DisplayWidth [![[version]](https://badge.fury.io/rb/unicode-display_width.svg)](https://badge.fury.io/rb/unicode-display_width) [<img src="https://github.com/janlelis/unicode-display_width/workflows/Test/badge.svg" />](https://github.com/janlelis/unicode-display_width/actions?query=workflow%3ATest)
 
-Determines the monospace display width of a string in Ruby. Useful for all kinds of terminal-based applications. The implementation based on [EastAsianWidth.txt](https://www.unicode.org/Public/UNIDATA/EastAsianWidth.txt), [the Emoji specfication](https://www.unicode.org/reports/tr51/) and other data, 100% in Ruby. It does not rely on the OS vendor (like [wcwidth()](https://github.com/janlelis/wcswidth-ruby)) to provide an up-to-date method for measuring string width in terminals.
