Ruby Base Text
What is Ruby: A Ruby textual annotation is an annotation, typically short, applied to a letter, word, phrase, or name that appears in narrative text. Ruby annotations can indicate, for example, pronunciation advice, notes for translation, semantic annotations, etc. Ruby is used with Japanese, for example, in Furigana, which typically uses Hiragana annotations on Kanji base text. Ruby is also used in Chinese Pīnyīn (a phonetic system for transcribing the sound of Chinese characters into Latin script) as well as for some Korean names. In display or print, the characters of a Ruby annotation are frequently placed above the characters they modify, in parentheses after the characters they modify, or to the right of vertically set text.
