FString not work well when containing Chinese characters

[anonymous_user_6f48ddab]

This string literal you are passing cannot properly hold Chinese characters.

From https://docs.unrealengine.com/latest/INT/Programming/UnrealArchitecture/StringHandling/index.html

In general, you should be using the TEXT() macro when setting string variable literals. If you do not specify the TEXT() macro, your literal will be encoded using ANSI, which is highly limited in what characters it supports. Any ANSI literals being passed into FString need to undergo a conversion to TCHAR (native Unicode encoding), so it is more efficient to use TEXT().

You need to have the literal converted to wide characters otherwise it will try to parse it as a pure ansi string which will be invalid.

EDIT: so with an example:

FString m = TEXT(“你”);
