[Q] [Root] How to change status bar text's font? topic

Guys, I want to change only status bar fonts (clock,date,battery,carrier label). Can any body tell me which files should I edit to do this? Or which files should I select to install font for only status bar fonts? I have downloaded some .ttf fonts, but where I should put these? I just want to change status bar fonts, not whole system fonts.
Any root guide or windows tool guide will be appreciated.
Thanks in advance.
