in reply to Vertical Tab (\x0b) in XML::LibXML

Vertical tabs (U+000B) are not allowed in XML documents. 

Char ::=
   #x9 | #xA | #xD |
   [#x20-#xD7FF] |
   [#xE000-#xFFFD] |
   [#x10000-#x10FFFF]

I don't know why I get a different error from the two inputs in your example, but I do get an error from both.

Update: Just noticed you knew U+000B isn't allowed in XML, in which case I don't get the question.

    When the encoding is specified, toString generates invalid XML without any error. In real life, this gets sent to a different XML processor that chokes on it. My question is why the behaviour is different, and whether there is something that should prevent me from submitting a bug report.

        No errors, no warnings. Maybe a different version of the underlying C library?

        Update: Thanks anonymous. 2.9.1, 2.0018 here.
