@DebayanChakraborty I was having the same issue on Ubuntu 16. I fixed it by installing @coolwanglu's fork of fontforge and rebuilding pdf2htmlEX.

the fork of fontforge is available here: https://github.com/coolwanglu/fontforge

@DebayanChakraborty I still got the same issue (focused on Arial Unicode MS) on CentOS 6.5 although I've installed @coolwanglu's fork of fontforge. The log is following by using --debug 1:

Curiously, I can get the right output to the same PDF file on Windows 7 even if there were some error messages like the below:

Internal Error: Attempt to output 457668 into a 16-bit field. It will be truncated and the file may not be useful.
A ligature index is invalid. (60000+ times)

Fortunately, the output is right to most of PDF file in my case.
