Unicode and XML Schema question

[pramenjatjek]

How can you represent a unicode character, for example an em dash, in an XML document through a schema?

Do I need to create an empty tag in my xml document (eg, <em/>) and then refer to this empty character in a schema? I found some information about \p{} which would represent a character. So would this then be \p{—}? How is this put in a schema though?

Thank you

I'm not what you're asking.

It sounds like you want to require documents that conform to your schema to have only a certain character in a certain element.

If so, then you can add a enumeration to that element that contains that character.

If you want to make sure that a certain element *contains* your character (there may be other characters in there too), I'm not sure how to require that -- a regular expression, maybe? Anyone?
