 As commented, it's currently incomplete:

 {{{#!cpp
         // XXX: this implementation is not entirely correct.  for example,
 it
         // should escape double-quotes if they appear in the character
 string.
 }}}

 we need to complete it.  Note that we use this conversion to store
 data in sqlite DB, so we need the fix pretty soon.

 BIND 9 has corresponding subroutine: lib/dns/rdata.c::txt_totext().
 Check that implementation and learn from it for this task.
