You cannot combine multiple characters to form the composed one. If there is Unicode character for this combination, you can use it directly. If it is not displayed correctly, it means your font doesn't contain this character and you need to switch to the font with broader character support.
You can if, as jmt pointed out, one of the characters (the dot, in this case) is a Unicode combining diacritical mark. At least you can in systems I've used, for most fonts. Systems I've used in this case means XeLaTeX (a Unicode-aware version of LaTeX) and Microsoft Word. I have not used the XSL-FO transform, but hopefully it works there too.
There may of course be Latin fonts where the dot-over is not defined, and there might possibly be fonts where it is defined but where it doesn't position itself correctly over some base characters (particularly where there is more than one diacritic, i.e. stacked diacritics). Fonts should come with a chart that tells what code points they handle, but that information can sometimes be difficult to find.
