Hi Raul,
I guess xalan supports almost all unicode characters.
It may show a question mark or a rectangle box as output if its cannot understand the unicode character that you specify, like & # x 2160;
Finding the correct Unicode for math symbol is a real task. Please read the spec from w3c http://www.w3.org/TR/REC-xml#CharClasses
i hope you visited the mathml site at http://www.w3.org/Math/ , there may be some free tool which could help you.
Regards
Balaji

Balaji,
I'm not sure Xalan needs to understand these Unicode characters, since Raul encodes them as character references (the number of the particular Unicode character it stands for).
I doubt Xalan tries to convert the character references to the actual characters they refer to.
On the other hand, the rendering software must understand these character references.
Cheers,
Dan

you are right!. Xalan will not try to convert them into actual characters.when its comes to FOP processor, the FOP tries to convert the unicode characters in to actual characters with the help of supplied map file,xalan and xerces.If the output is PDF the map file will be a of TTF.
For HTML rendering,Raul may try to supply this map file in form of font file in <font> or <span> tag ,so that IE or netscape will show it as actual character.

Thanks Balaji. I spoke with our front-end guru and he said that in one case, they created actual images that represented the mathematical symbols because they couldn't find these particular math fonts.
Good luck Raul!
