The RSS 1.0 +and RSS 2.0 feeds from the same Planet are fine. All three files +are in fact correct UTF-8, but IkiWiki mis-parses the Atom. + +This turns out to be a bug in XML::Feed, or (depending on your point +of view) XML::Feed failing to work around a design flaw in XML::Atom. +When parsing RSS it returns Unicode strings, but when parsing Atom +it delegates to XML::Atom's behaviour, which by default is to strip +the UTF8 flag from strings that it outputs; as a result, they're +interpreted by IkiWiki as byte sequences corresponding to the UTF-8 +encoding. IkiWiki then treats these as if they were Latin-1 and +encodes them into UTF-8 for output. + +I've filed a bug against XML::Feed on CPAN requesting that it sets +the right magical variable to change this behaviour. IkiWiki can +also apply the same workaround (and doing so should be harmless even +when XML::Feed is fixed); please consider merging my 'atom' branch, +which does so. --[[smcv]] + +[[!tag patch]] |
