PhoneticCharacters Property [Excel 2003 VBA Language Reference]
Returns or sets the phonetic text in the specified Characters object. Read/write String.
Instead of using this property, you should use the Add method of the Phonetics collection to add phonetic information to a cell, and use the Text property of the Phonetic object to return or set the phonetic text strings in a cell.
You can use this property only with Characters objects that are based on a single cell.
This example replaces the fourth character from the beginning of the text in the active cell with Furigana characters.
ActiveCell.Characters(1,3).PhoneticCharacters = ""
