Question mark problems

[mr_mind]

Alright well in apache regex the ? means that the character preceding  it is optional. For example if you were to do colou?r you would match both colour and color. Now what i want to be able to do is use the question mark as a literal character instead of letting it have the function i previously stated. I tried escaping it as you would any other character but to my dismay this did not work. When i wrote www.example.com/fakeuri.php\? in the mod rewrite it thought that i told it to look for www.example.com/fakeuri.php and www.example.com/fakeuri.php\ which is not what i want.
