Supposedly, fopen() can read unicode text file if the text file is saved with UTF-8 encoding, e.g. fid=fopen('test.txt','r','n','UTF-8'). But in your case, I think as long as you can distinguish those different characters, you can then process it for whatever you need. Assume the test.txt file contains the line shown in your question, the following lines can read it.
fid=fopen('test.txt','rt');
Maze=[];
while ~feof(fid)
Line=fgetl(fid);
Maze=[Maze;Line];
end
fclose(fid);
Maze
isspace(Maze)
[Xs,Ys]=find(Maze=='S')
[Xg,Yg]=find(Maze=='G')
Maze =
