抑扬符号 meaning in English

circumflex symbol

Because rewriting a legacy application is seldom an option , you need a conversion routine that will convert unicode characters into a set that is acceptable to the application - for example converting " into a straight " i " removing the circumflex
因为很少有可能重写遗留系统，就需要某种转换例程将unicode字符转化成应用程序能够接受的字符集，比如将“ ”转化成直接的“ i ” （去掉抑扬符号）。
