> 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:
> İSO-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.
