Defining Furigana options
The Furigana option is a Japanese-specific feature. The option allows a user to specify that the Kana reading for Japanese text in one field be entered automatically to another.
Japanese text is composed of Kana (Hiragana and Katakana) and Kanji (characters). Kanji characters have multiple readings, and the Unicode ordering of these characters is arbitrary. Thus, to sort Kanji characters in a truly meaningful way, it is necessary to sort by the Kana (phonetic syllabary) reading intended for each character. The Furigana field is intended as a shadow field into which the Kana readings for Kanji can be entered.
To create a Furigana field, the user creates two text fields in Manage Database, then selects the field into which Kanji will be entered (the “parent” field), and establishes a link, via the Use Furigana Field option, to the field into which the corresponding Kana readings will appear (the “child” field).
A Furigana “child” field defined with this option maintains a connection to its “parent” field data. When the user inputs Japanese text into the parent field, FileMaker Pro guesses the intended Kana reading of the entered characters, based on how the characters have been input, and enters this text in the Furigana field.
To set Furigana options for a field:
With the database open, choose File menu > Manage > Database.
Note  To set options for fields in Table View, right-click the column heading for the field, then choose Field > Field Options from the shortcut menu, then skip to step 6.
Click Options (or double-click the field name).
Click OK to close the Options for Field dialog box, or click another tab to set additional field options.
