.... depending on the font you are using. If the font do not have italics, they will not be shown. Sometimes, in my experience, italics are also very faint and almost undistinguishable from normal characters.
To recap, if you are not sure the ebook has italics, first maybe check on a PC ereader. If they appear there, then it is a font problem lacking italics, therefore change to a font which has italics. As easy as that.
