[Yafes Sahin]"Is there a good way to solve that problem? "
Sure: use a typeface without proportional spacing, like Courier. Since all the characters are the same width, the tabs will be consistent.... but since there will be no proportional spacing, the width between characters will look odd.
You MIGHT be able to turn off proportional spacing for any font, but I've never had to use it. You can double-check in AE Help.
