Status: RESOLVED DUPLICATE of bug 1174580

(Thunderbird :: Message Reader UI, defect)

Steps to reproduce:

I upgraded from version 31.7.0 to 38.0.1 then some of my emails with Chinese characters are not correctly displayed.


Actual results:

All the Chinese characters in the mail are not correctly displayed.
However, if I manually choose View->Character Encodeing->Chinese, Simplified (even if it's already checked), the reader goes back to normal until I view other emails and go back to the problematic email again.
Somehow, some of the emails does not have the encoding issue. I can't find out the reason. So I attached 2 mails for you to analyse.


Expected results:

Encoding should be automatically detected and Chinese characters should be displayed correctly.
