text characters is far on from another

I followed the http://www.tutorialsforblender3d.com/GameDoc/Text/Text_GLSL_Quick.html and managed to display the Hello word.

but when I tried to implement this in my fps game, I got a big location difference between the characters.

Hi
here you can see the white planes .

Hello
enter edit mode, select all vertices and scale down!
Then outside edit mode, rescale, if needed!
Bye

No no no no, scale up to the original size in edit mode, then enter object mode and scale down.

thanks that did the trick
