calvin-c is right. Boxes with an X in them indicate that the font being used does not contain those characters.
The usual solutions are either
1. to try using an app which either uses a fuller default font or lets you specify your own better font (which does contain the characters).
2. to embed the better font in the epub yourself, using Sigil or calibre, before transferring to the tablet. This would only work if the DRM was removed first.
