The unicode standard dicusses a syntax for identifiers here [1]. Note that determining if two identifiers are equal needs to invoke the unicode normalization machinery, it is not just a matter of knowing what is a letter and a symbol. That being said, I really don't see unicode identifiers as a must have feature, au contraire.
Regarding the use of math symbols, I think Alain is right, it should be addressed as a presentation issue. Actually that's the way Fortress [3] handles it, as a rendering issue.
Speaking of using UTF-8 in source files, it was recently pointed out to me that this is not a problem as long as you use only ASCII identifiers. The advantage is that you can have UTF-8 string literals in your source code.
