Hi, 

I understand that you want to find whether the encoding of the specified text file is GBK or UTF-8.

Below is the MATLAB code to check the encoding of a txt file:

% Specify the file path and name 
filename = 'untitled.txt'; 

% Read the file as a binary stream 
fid = fopen(filename, 'rb'); 
data = fread(fid); 
fclose(fid); 

% Check if the file is UTF-8 encoded 
isUTF8 = isequal(data(1:3), [239; 187; 191]); 

% Check if the file is GBK encoded 
isGBK = false; 

try 
decodedText = native2unicode(data, 'GBK'); 
isGBK = true; 
catch 
% GBK decoding failed, indicating it's not GBK encoded 
end 
 
% Check the encoding 
if isUTF8 
disp('The file is in UTF-8 format.'); 
elseif isGBK 
disp('The file is in GBK format.'); 
else 
disp('The file encoding is not UTF-8 or GBK.'); 
% You can assume it is encoded in another format 
end 

Hope this helps.
