In HTML 4.0, this is +specified as the character entity uuml. Ikiwiki 2.47 running on Debian etch does +not seem to understand that entity, and decides not to un-escape any markup in +the feed. This makes the feed hard to read. + +The following is the test input: + + <rss version="2.0"> + <channel> + <title>testfeed</title> + <link>http://example.com/</link> + <language>en</language> + <description>example</description> + <item> + <title>ü</title> + <guid>http://example.com</guid> + <link>http://example.com</link> + <description>foo</description> + <pubDate>Tue, 27 May 2008 22:42:42 +0000</pubDate> + </item> + </channel> + </rss> + +When I feed this to ikiwiki, it complains: +"processed ok at 2008-05-29 09:44:14 (invalid UTF-8 stripped from feed) (feed entities escaped" + +Note also that the test input contains only pure ASCII, no UTF-8 at all. + +If I remove the ampersand in the title, ikiwiki has no problem. However, the entity is +valid HTML, so it would be good for ikiwiki to understand it. At the minimum, stripping +the offending entity but un-escaping the rest seems like a reasonable thing to do, +unless that has security implications. |
