FString TestStr = TEXT(“中文”);
TCHAR_TO_ANSI(*TestStr); // the convert result is “??”

TCHAR_TO_ANSI can’t convert chinese characters to ANSI. How to fix this?

P.S. This same code works in UE3.

The internet tells me that ANSI-Char is 8-bit, which can represent 256 characters. Chinese cannot fit into a ANSI-Char. If that worked in UE3 than ANSI-Char in UE3 was not actually ANSI-Char. It is not possible for ANSI to hold chinese characters. This is what it can hold.

ANSI use 2 bytes to represent chinese characters. For example

char ANSI(GBK)

中 0xD6D0

char ANSI(GBK)

文 0xCEC4

in UE3, TCHAR_TO_ANSI use WideCharToMultiByte to covert between TCHAR and ANSI on Windows
