Hi,

I am working on a web stie which requires unicode support.

I mostly works; I have spent few days on the following issues with no  
solution so any help is very much appreciated.:

1. I would like to decompose a unicode string into individual  
characters and then compose it again. I can do first part with  
mystring.chars[i]. How can I put the string back from such  
character codes. Integer.chr does not work on unicodes

2. How can I URL encode them (I guess I could, if I can get the first  
question answered)

3. Is there a function to convert them into HTML/XML entities?

Thanks,
