I used to work with QuarkXPress and have never experienced problems with italic/bold when importing from Word (exept for DOCX!). Quark imports everything also faux italic/bold no matter the fonts and so on … So I was chokked when I started to use InDesign, I thought it was superior to Quark in that respect! With InDesign one have to go through the whole original Word-file and change all fonts and attributes first. There have to be made a solution for this.
