Conversion of UTF-8 to XML.

[Donald A. Pellegrino Jr.]

I have found Xerces-C to have handy utility functions for string operations, 
such as Transcode. I have a need to write some UTF-8 data in memory out to an 
XML file. Is there a short series of existing functions available which I could 
use to ensure the simple specials such as the ampersand (&) are converted to 
XML text specials such as (&) in my output?
