   | 14058    | Fix dblink._unmerge_pkgfiles() to use the correct version   |
   | zmedico  | of perform_md5 when it falls back to utf8 encoding.         |

   | 14059    | In perform_checksum(), encode the filename with correct     |
   | zmedico  | encoding before passing to spawn (for prelink), and enable  |
   |          | strict encoding behavior in _perform_md5_merge().           |

   | 14060    | Make _generate_hash_function() use _fs_encoding to encode   |
   | zmedico  | the filename (if it's not already encoded), and enable      |
   |          | errors='strict'.                                            |

   | 14061    | Make movefile() use process.spawn() instead of              |
   | zmedico  | getstatusoutput() when calling MOVE_BINARY, since spawn     |
   |          | will pass encoded file paths directly as arguments.         |

   | 14062    | Update import to import portage.os (with unicode wrappers), |
   | zmedico  | and use _unicode_encode() and _content_encoding for         |
   |          | encoding unicode env vars in spawn().                       |

   | 14063    | Remove ACCEPT_PROPERTIES variable generation code which     |
   | zmedico  | isn't needed since, unlike ACCEPT_LICENSE,                  |
   |          | ACCEPT_PROPERTIES isn't passed into the ebuild environment. |

   | 14064    | Fix typo.                                                   |
   | zmedico  |                                                             |

   | 14065    | Remove ACCEPT_PROPERTIES filtering since it's filtered on   |
   | zmedico  | the python side.                                            |

   | 14067    | Prepare 308 messages to localization.                       |
   | arfrever |                                                             |
