Aspose.Cells for Java脚本通过C++允许你访问和更新单元格的丰富文本部分。为此，可以使用Cell.characters和Cell.characters属性。这些属性将返回和接受FontSetting对象数组，用于访问和更新字体的各种属性，如字体名称、字体颜色、加粗等。
访问和更新单元格的富文本部分
以下代码演示了使用源Excel文件中Cell.characters和Cell.characters属性的用法，你可以从提供的链接下载该文件。源Excel文件在A1单元格中有丰富文本。它有3个部分，每个部分使用不同的字体。下一段代码访问这些部分，并用新字体名称更新第一个部分。最后，它将工作簿保存为输出Excel文件。打开后，你会发现第一部分的字体已更改为**“Arial”**。
