let me explain first, what I am using to display the multilingual in my browser.
my operating system is Windows 95, Browser - Netscape Communicator 4.7 and Arial Unicode MS font with UTF-8. I am not much
confident about the sequence is being used by the Arial Unicode MS, Code2000, TITUS and other Aksharmala to represent the
glyphs and surrogates. Because when I wanted to display the characters, which has been written to used Aksharmala, TITUS
and Code2000, somewhere I got characters mess with my browser. Is that due to private use area, which has been used
different by each font vendors.

without making myself perfect to identify the actual problem, I can not say anything about your use.
