Using the latest version of phantomjs v1.9.7, there is a problem with displaying some characters on my production server. No problem on dev server.
When rendering the phantomjs.org main page, fonts with a strong tag or some bold type, such as 700em, display correctly, but the normal font is not.
I have not noticed this problem with other urls yet.
Also, all Chinese characters from any URL (which I have checked so far) display with fields on the production server, but correctly on the dev server.
I do not know what the problem is.
Here is a screenshot of the http://phantomjs.org section for each server:
production server - debian 7 stable

dev server - debian 8 testing
