Package: hplip
Version: 3.16.11+repack0-2
Severity: important
Tags: upstream

Dear Maintainer,

   * What led up to the situation?
   Trying to print a document with non ASCII characters in its title.
   This led to a UnicodeDecodeError:

   D [03/May/2017:10:59:23 +0200] [Job 1345] Traceback (most recent call
   last):
   D [03/May/2017:10:59:23 +0200] [Job 1345] File
   \"/usr/lib/cups/filter/hpps\", line 203, in <module>
   D [03/May/2017:10:59:23 +0200] [Job 1345] os.write(output_fd,
   to_bytes_utf8(\'@PJL SET JOBNAME=\"%s\"\\x0a\' % title))
   D [03/May/2017:10:59:23 +0200] [Job 1345] File
   \"/usr/share/hplip/base/sixext.py\", line 109, in to_bytes_utf8
   D [03/May/2017:10:59:23 +0200] [Job 1345] return s.encode(\"utf-8\")
   D [03/May/2017:10:59:23 +0200] [Job 1345] UnicodeEncodeError:
   \'utf-8\' codec can\'t encode character \'\\udce2\' in position 47:
   surrogates not allowed

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

   Manually fix "/usr/share/hplip/base/sixext.py" by applying the patch
   proposed in "https://launchpadlibrarian.net/213208457/sixext.patch";
   

   * What was the outcome of this action?
   It fixed the problem, printing works fine now.
