[bug-gettext] bug #52932: XML doesn’t default to UTF-8

[Roumen Petrov]

There is no exactly default encoding for xml as specification requires 
xml processor to support UTF-8 and UTF-16 encoding - for more details 
see  chapter https://www.w3.org/TR/xml/#charencoding .

Next encoding is required if is not UTF-8 or UTF-16. Actually is more 
complicated. Let me quote from specification (same chapter) : "In the 
absence of external character encoding information (such as MIME 
headers), parsed entities which are stored in an encoding other than 
UTF-8 or UTF-16 /MUST/ begin with a text declaration ...."

So if there is no explicit specification of according to standard 
encoding is either UTF-8 or UTF-16.
