That would violate the HTTP spec for the User-Agent header (RFC 7231 §
5.5.3, RFC 7230 § 3.2.6):

     User-Agent = product *( RWS ( product / comment ) )
     product         = token ["/" product-version]
     product-version = token

     token          = 1*tchar

     tchar          = "!" / "#" / "$" / "%" / "&" / "'" / "*"
                    / "+" / "-" / "." / "^" / "_" / "`" / "|" / "~"
                    / DIGIT / ALPHA
                    ; any VCHAR, except delimiters
