CorelDRAW Graphics Suite X6 :: Specific Size Text And Kerning

i need to type a text in corel of a specific size in millimeters. i know there is a setting in the corel options that allows sizing text directly in millimeters, instead of points. problem is that i need to type in romanian language, which has these points and marks above or bellow certain characters like A, T or S and the size in millimeters that i enter in the text size box will give that size to the "marked" characters, whereas i need only the pure, normal letter to be given that size. for example, an S with a comma under it.. i want just the S to be given a certain size and the comma scaled proportionally. furthermore, i would like to add an even spacing between all the letters that i type, also expressed in millimeters. i could only find a percent expressed setting in the text properties panel, i dont even know percents of what.

how can i do this in the fastest way possible, or automatically?
