Actionscript3 / Flex中的HTML特殊实体代码

导读：我有一个Flex / Actionscript 3应用程序,它在Text元素中显示RSS提要.它删除了任何 HTML格式,但它没有正确处理 HTML特殊实体代码 – 它是渲染 mdash作为文字字符串而不是用em-dash等替换它.是否有任何系统的方法我可以处理它那些代码是否正确,或者我是否需要

HTML格式,但它没有正确处理
HTML特殊实体代码 – 它是渲染& mdash作为文字字符串而不是用em-dash等替换它.是否有任何系统的方法我可以处理它那些代码是否正确,或者我是否需要手动替换那些字符串正则表达式？
编辑：相关的Flex行为的某些方面：text和htmlText正确处理有限的字符子集而无需进一步调整 – & lt,& gt,& nbsp等等.(事实上,文本实际上处理它们比htmlText好一些,因为后者将& lt;视为字面值小于字符.)但是有一个更大的字符集(& deg,& mdash,以及许多其他字符)未被处理正确 – 至少,不是默认. 解决方法
这是一种方式：
