   Hi, could I know which version were you trying? 
   
   I tried to create timeseries with path `root.sg.d1."C:\"` on `0.12-snapshot` and got an error message `Msg: 315: The timeseries name contains unsupported character. root.sg.d1."C:\" is not a legal path`.
   
   I do know why this error thrown. We have a `ID_MATCHER` field in IoTDBConfig class. If the path node name doesn't match this, the creating will fail. 
   
   Also, antlr will check if the name is following the rule defined in SqlBase.g4 when create timeseries using JDBC api.
   
   BTW, the matcher and the antlr rule need to be updated indeed.
