The normal result of upper part of download2_4.pdf

Version:           0.10.2 (using KDE 4.4.2) 
OS:                Linux

http://www.crossstrait.nccu.edu.tw/download/download2_4.pdf(All Chinese characters are broken. The correct result is in the attached file.)
http://psroc.phys.ntu.edu.tw/bimonth/v27/395.pdf (Title and subtitle characters are good but the content characters are disfigured)

According to a responder in poppler mailing list, poppler-qt4 has a switch to enable hinting in all fonts in a document (disabled by default), but
Okular does not touch the switch.

P.S. The above two PDF files are correctly shown by Xpdf ver.3.02.

Reproducible: Always

Steps to Reproduce:
Just open the file

Actual Results:  
Disfigured Chinese characters

Expected Results:  
Normal Chinese characters

Something goes wrong. The first hyperlink should be:

Can't tell about the second one, but the first one looks exactly like the attached png so I am closing the bug, if you can still reproduce this issue with newer KDE/poppler versions please reopen this bug.
