No, there is no reason to convert the file to a text file. AES can encrypt the binary contents of the file directly, because any file can be interpreted as sequence of bytes.
fid = fopen(FileName, 'r');
if fid == -1, error('Cannot open file'); end
data = fread(fid, Inf, '*uint8');
fclose(fid);
All AES implementations I've ever seen work on Byte arrays.
