branch: master
commit d57bb0c323c326518d9cc974dc794f9e23a51917

    Treat passed strings as raw-text when percent-escaping in epg
    
    The strings contained in gpg keys can contain UTF-8 data, but can also
    use percent-escapes to encode non-ASCII chars.  When converting those
    escapes, use 'raw-text' coding system rather than 'string-to-unibyte',
    since the latter signals an error for non-ASCII characters.
    
    * lisp/epg.el (epg--decode-percent-escape): Convert the passed
    string to raw-text before treating percent escapes (Bug#38512).
