Dominik Stadler updated XERCESC-1270:
-------------------------------------

    Attachment: TestXMLFormatter.h

This is a testcase that shows that xerces includes the character 0x0e in the 
XML although the default setting for XMLFormatter is to fail on unrepresentable 
characters.

> XMLFormatter can produce XML that fails parsing

>      Project: Xerces-C++
>         Type: Bug
>   Components: Utilities
>     Versions: 2.3.0
>  Environment: Windows 2000, Xerces 2.3.0, VC++ 6.0
>     Reporter: Dominik Stadler
>  Attachments: TestXMLFormatter.h, Test_xe9.xml

> One of our classes uses an XMLFormatter to generate a text-representation of 
> an XML-String. We use this to escape the characters correctly. 
> The XMLFormatter uses the default setting to fail on unrepresentable 
> characters, see 
> http://xml.apache.org/xerces-c/apiDocs/classXMLFormatter.html#z549_0
> When we have an character with ascii-value of 0x0e in the string, the 
> XMLFormatter escapes this as "" which looks ok, but according to the XML 
> Standard, only 0x0a, 0x0d and 0x09 are valid ascii-characters below 0x020!! 
> See also http://w3c.org/TR/2004/REC-xml-20040204/#charsets
> Consequently when we try to parse the generated xml-file again with Xerces, 
> we get an error "Invalid character reference".
> In my opinion, XMLFormatter should report an error if characters below 0x020 
> (and not 0x0a, 0x0d and 0x09) are encountered and unrepFlags is set to 
> Unrep_Fail. This currently let's me generate invalid XML-Files with 
> XMLFormatter.
