Plugin Name: Latin-2-UTF
Plugin URI: http://kackreiz.net/wordpress.php
Description: Since old versions of Wordpress used Latin-1 encoding for all the
content, displaying these old entries through a new WP Version (using UTF-8)
looks ugly. This Plugin converts the German Umlauts &Auml;...&uuml; and &szlig;
from Latin1 to UTF8.

Version: 1.3

WARNING:
THIS PLUGIN COMES WITHOUT ANY WARRANTY, USE IT ON YOUR OWN RISK.
I WON'T TAKE ANY RESPONSIBILITY FOR DAMAGES CAUSED BY USING THIS PLUGIN

INSTALLATION:
1. Copy into wp-content/plugins and activate it in the admin-panel.
2. The filter latin2utf is now used automatically on any of your text-snippets
   (like "the_content", "comment_text", etc.)More information on this can be
   found here:
                  http://codex.wordpress.org/Plugin_API
   As you can see, upon loading the plugin, filters for the content and
   comments are automatically installed.
3. In the Line marked with "EDIT HERE" you have to adjust the date of
   your change to wp-1.2 (or higher). Alle posts and comments before that
   date are converted, the rest is left as it is.
   The format for that date is "Ymd" (=YYYYMMDD, see php.net/date for hints),
   the same format used in the two lines above it.
