I encountered a problem sending the string this’s my code: Socket->Send((uint8*)TCHAR_TO_UTF8(*StringValue), StringValue.Len(), SocketSent); I use FString.Len() to get the length of FString if “StringValue” is English , this’s normal but if “StringValue” it’s Chinese , this’s wrong , it’s lengt…

FString is just an array of TCHARs. FString::Len() will return the size of that array. If you see more characters than FString::Len() is reporting then most likely there are two (or more) Chinese characters within the same TCHAR in the FString array.

How to get fstring size?
