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
:
gem 'unicode_scanner'
Usage
The UnicodeScanner
object responds to exactly the same API as
StringScanner,
with the exception of the following methods:
getbyte
- any obsolete methods
