# SUMMARY

Can not display CJK characters with Adobe's OTF Fonts

# STEPS TO REPRODUCE
1. I opened a pdf file with CJK characters. This pdf file uses 'Adobe Song
Std.otf', which could be downloaded here: [Adobe Song
Std.otf](https://github.com/mingchen/mac-osx-chinese-fonts/blob/master/Adobe%20Simple%20Chinese%20Fonts/AdobeSongStd-Light.otf)

# OBSERVED RESULT

1. All CJK Characters can not display (showed nothing), but English char and
numeric characters could display.
2. Opening the same pdf file with chrome/chromium or firefox or adobe acrobat
reader works without problems.

# EXPECTED RESULT

Show CJK characters.
