differenct space needed for different letters?

[dongjiang tang]

Hi, I have mutiple line of text in one block in the header for my page, I make each line the exactly same number of letters(same string length), then I found out that the actual space each line takes is not the same, some are longer and some are shorter, just like below. Is there any way to make each line appears to be the same 'actual length' ?   start of line ccccccccccccccc ccccccccccccccccccccccccccccc ccccccccccccccccccend of line dongjiang
