Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/variant. To experiment with that code, run bin/console for an interactive prompt.

Compatible kanji changes its glyph shape by Unicode normalization.Therefore, by using compatibility_to_unified method, convert it into integrated Chinese character with variant character selector so that character shape does not change.

Also, IVS has duplicate characters of the same form registered in Adobe-Japan 1 and Hanyo-Denshi.Conversion can be done mutually by using adobe_to_hanyo method and hanyo_to_adobe method.


Add this line to your application's Gemfile:

gem 'variant'

And then execute:

$ bundle

Or install it yourself as:

$ gem install variant


compatibility_to_unified: Conversion into integrated kanji including variant character selector can be performed by executing on sentences including compatible kanji

adobe_to_hanyo: Convert from Adobe-Japan 1 registered in IVS to Hanyo-Denshi of the same character shape

hanyo_to_adobe: Can be converted from Hanyo-Denshi registered in IVS to Adobe-Japan1 of the same character shape
