Bug#28862 Extended Latin1 characters get lost in CVS engine

  Problem: Temporary buffer which is used for quoting and escaping
  was initialized to character set utf8, and thus didn't allow
  to store data in other character sets.
  Fix: changing character set of the buffer to be able to
  store any arbitrary sequence of bytes.
