I find difficult in writing in text pad,which is last line,while writing numbers and special characters,it displat wrong result

foe ex IND 77-4 IT DISPLAY AS IND 7Zm

clc, close all, clear all

imagen=imread('samp22.jpg');

    imagen=rgb2gray(imagen);
end
% Convert to BW
threshold = graythresh(imagen);
imagen =~im2bw(imagen,threshold);
imagen2 = imagen;
figure,imshow(imagen2);
% title('before bwareaopen')
% Remove all object containing fewer than 15 pixels
imagen = bwareaopen(imagen,15);
imagen3 = imagen;
