> When the default locale is set to the Turkish language, using the XmlStreamReader constructor
on an XML stream with a prolog including the ISO-8859-1 charset name in lowercase as its encoding
throws a UnsupportedEncodingException (java.io.UnsupportedEncodingException: ─░SO-8859-1).
> Example XML prolog : <?xml version="1.0" encoding="iso-8859-1"?>
> This is apparently because the XmlStreamReader class uses String.toUpperCase() in its
getXmlProlog() function. It should rather use toUpperCase(Locale.ROOT) or toUpperCase(Locale.US)
as already done in the getContentTypeEncoding() function. Otherwise the behaviour can be different
depending on the default locale, as the dotted lower case i becomes a dotted upper case i
in the Turkish language, which not the case with other languages.
