How do I close the open gap in a character?

How do I close the gaps in a single character. I want to close characters like e,c etc so that it forms a circular object. imclose doesn't seem to do it perfect.

i=imread('e.jpg');
i=im2bw(i);
figure; imshow(i);
se = strel('disk',4);
i=imclose(i,se);
figure; imshow(i);
