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.
Simply add this gem to your project's Gemfile:
gem 'unicode_scanner'The UnicodeScanner object responds to exactly the same API as
StringScanner,
with the exception of the following methods:
getbyte- any obsolete methods
