 If you've been using Laconica 0.6, 0.5 or lower, or if you've been
 tracking the "git" version of the software, you will probably want
 to upgrade and keep your existing data. There is no automated upgrade

+Laconica 0.7.4 introduced a fix for some incorrectly-stored
+international characters ("UTF-8"). This fix is not
+backwards-compatible; installations from before 0.7.4 will show
+non-ASCII characters of old notices incorrectly. This section explains
+what to do.

+0. You can disable the new behaviour by setting the 'db''utf8' config
+   option to "false". You should only do this until you're ready to
+   convert your DB to the new format.
+1. When you're ready to convert, you can run the fixup_utf8.php script
+   in the scripts/ subdirectory. If you've had the "new behaviour"
+   enabled (probably a good idea), you can give the ID of the first
+   "new" notice as a parameter, and only notices before that one will
+   be converted. Notices are converted in reverse chronological order,
+   so the most recent (and visible) ones will be converted first. The
+   script should work whether or not you have the 'db''utf8' config
+   option enabled.
+2. When you're ready, set $config['db']['utf8'] to true, so that
+   new notices will be stored correctly.
