What’s Rubi?

Ruby characters are small, annotative characters that are usually placed above logographic characters when writing languages with logographic characters such as Chinese, Japanese or Korean to show the pronunciation.

Why Ruby Characters?

Ruby may be used for different reasons:

  • because the character is rare and the pronunciation unknown to many—personal name characters often fall into this category;
  • because the character has more than one pronunciation, and the context is insufficient to determine which to use;
  • because the intended readers of the text are still learning the language and are not expected to always know the * pronunciation and/or meaning of a term;
  • because the author is using a nonstandard pronunciation for a character or a term

How does it work?

Adding ruby characters couldn’t be easier. Just select your text. Click on the “Add Ruby Characters” button. Type your ruby characters and you’re all done.


  • Highlight you text. Set your ruby characters. All done.
