I also agree, but there are some occasions where such markup added in the middle of combining sequences are unavoidable (notably when adding meta-data markup for example in revision notices. But I agree that if the markup is intended to affect the rendering (including foreground/background colors), this should be avoided. combining sequences are intended to be rendered as a whole if they are in a document whose purpose is to be rendered (such as HTML files), but this does not apply to documents which are mostly structured data (such as XML data files, for example created when dumping out the content of a database table, or in data communication protocols based on XML for its transmission syntax, where even defective combining sequences are valid data and should also be valid Unicode plain text when the datatype of fields are really Unicode text). __________________________________________________________________ << ella for Spam Control >> has removed Spam messages and set aside Newsletters for me You can use it too - and it's FREE! http://www.ellaforspam.com
