"blank page" after each chapter with a strange symbol on it, how can I get rid of it?

I use Latex, document class is book. After each chapter, there is a page with page head and foot, and also a strange symbol on it, and the rest is blank. Then after this page a normal blank page is generated. Has anyone 开发者_如何学编程ever encountered such problem? How can I get rid of this "non-blank" blank page? Thank you very much and best wishes!

I have had a similar problem, and found that it depended on the mix of packages I had, and the order in which initialisation commands were made. I enclose my normal header. The only non-standard part is partpg which does for chapters what chappg does for chapters.

\documentclass[10pt,notitlepage]{book}%
\usepackage[a4paper,twoside,bindingoffset=0in,left=1.25in,right=1.25in,top=1in,
            b   ottom=1.5in,includemp,marginparwidth=1.25in,heightrounded,verbose]{geometry} 
\usepackage{sectsty} % Fancy section Headers.
\usepackage{fancyhdr} % Headers and footers.
\usepackage{parskip} % Paragraph layout - no indent, line space between.
\usepackage{tocbibind} % Include index, toc, and biblio in toc.
\usepackage[auto]{partpg} % Modified version of chappg to provide part-pageno type page numbering.

Make sure your chapter files are ANSI-encoded instead of Unicode. I have recent personal experience with Unicode files generating weird symbols that disappear after I convert them to ANSI.
