Hi Cong, I was intrigued by the question since I've never used the gsl_matrix_char type. It seems that for fscanf it will only accept signed integer in the range from -127 to 128 according to the width of a signed char.
This means that you could replace the letters by their equivalent ascii code or otherwise you have to write your customized function to parse the file.
