Hi,

this is a single problem from
http://lists.gnu.org/archive/html/lilypond-devel/2016-11/msg00090.html
about pdf-meta-data with guile2

In framework-ps.scm we have `metadata-encode' defined as part of
`handle-metadata'
There's the comment:
    ;; First, call ly:encode-string-for-pdf to encode the string (latin1 or
    ;; utf-16be), then escape all parentheses and backslashes
    ;; FIXME guile-2.0: use (string->utf16 str 'big) instead

`handle-metadata' finally returns
(ps-quote (ly:encode-string-for-pdf val))

Why did we do so at all?
In my (ofcourse limited) testings I see no difference doing directly:
(ps-quote val)
instead.

Thanks,
  Harm
