在Source Insight编程工具中显示unknown escape sequence: '\224'

这是为什么，怎么解决。

==== Compiling HttpFormHandlerEventLog.cpp (in Bfc/IpHelpers/Https)
==== Compiling HttpFormHandlerConnect.cpp (in Bfc/IpHelpers/Https)
../../../ResidentialGateway/Http/HttpFormHandlerRgDiagnostics.cpp:83:53: unknown escape sequence: '\224'
../../../ResidentialGateway/Http/HttpFormHandlerRgDiagnostics.cpp:86:53: unknown escape sequence: '\224'
对应代码：

char * BcmHttpRgDiagnosticsFormHandler::fMyLinkInactive = "

";
char * BcmHttpRgDiagnosticsFormHandler::fMyLinkActive = "";
