    plparser: Ignore case for UTF-8 encoding check in XML documents
    
    Don't try to convert from "utf-8" to "UTF-8" encodings, as those are one
    and the same, and iconv will fail when trying that.
    
    Encodings are defined in:
    https://www.iana.org/assignments/character-sets/character-sets.xhtml
