About

Did you know that StringScanner splits codepoints? Neither did I. This one doesn't.

When would I want to use this? When you want to use StringScanner on a Unicode (UTF-n) string.

When would I not want to use this? If you're interested in speed. This is slower than StringScanner because a) it's not written in native C, and b) it's slower to traverse Unicode strings anyway because characters can have varying byte sizes.

Installation

Simply add this gem to your project's Gemfile:

ruby gem 'unicode_scanner'
