In the german Wikipedia there is an image with the filename "Kohlenstoffnanoröhre-Animation.gif" ('cur'-DB-Entry 335479). I don't know why, but the "ö" is not encoded the usual way with %C3%B6, but with %6F%CC%88, which is an "o" followed by special dieresis for the previous letter: so both encodings are correct "ö"-encodings. But MediaWiki only shows Pages with "ö" in the %C3%B6-encoding. So even when calling directly the %6F%CC%88- encoding I get an header-redirect to the %C3%B6-page (Location: http://de.wikipedia.org/wiki/Bild: Kohlenstoffnanor%C3%B6hre-Animation.gif). It's now impossible to view that page or delete it.
The image is already replaced by a well named version (http://de.wikipedia.org/wiki/Bild: Kohlenstoffnanoroehre_Animation.gif), so the misspelled one has to be deleted. Thanx.
Upping priority
This should have been corrected some time ago. Confirmed?
Please look at http://de.wikipedia.org/w/index.php?title=Kohlenstoffnanor%C3%B6hre&oldid=3850707 and click on the only image on this page. Don't know if the creation of such images is fixed but this one still exists ;)
Hallo! If you select view page source in your browser for http://de.wikipedia.org/w/index.php?title=Kohlenstoffnanor%C3%B6hre&oldid=3850707 you will can find http://upload.wikimedia.org/wikipedia/de/e/e2/Kohlenstoffnanoro%CC%88hre-Animation.gif This is the image that should be deleted which does not show up at [[de:image:Kohlenstoffnanoröhre-Animation.gif]]. re: comment 1 Today the image is available at [[de:image:Kohlenstoffnanoroehre-Animation.gif]] because of [[commons:image:Kohlenstoffnanoroehre_Animation.gif]]. re old url: http://de.wikipedia.org/w/index.php?title=Spezial%3AAllpages&from=Kohlenstoffnanor&namespace=6 a) Please note that [[Special:Allpages]] is not suitable to identify all medias because {{ns:Media}} is not supported at Allpages or the page which is subject of this bug is not shown at Special:Allpages?namespace=6 because *another* subsequent bug. b) Please note that [[Special:Imagelist]] can not be used either because no filter functionality is available any more. c) The image can neither be found in the upload log with http://de.wikipedia.org/w/index.php?title=Special:Log/upload&page=image:Kohlenstoffnanor%C3%B6hre-Animation.gif nor with http://de.wikipedia.org/w/index.php?title=Special:Log/upload&page=image:Kohlenstoffnanoro%CC%88hre-Animation.gif The reason might relate to earlier versions of [[Special:Upload]] / [[Special:Log]]. Please note that %CC%88 stands for COMBINING DIAERESIS - U+0308 http://www.fileformat.info/info/unicode/char/0308/index.htm Entity (decimal) ̈ (hex) ̈ UTF-8 (hex) 0xCC 0x88 (cc88) If this file "survived" the databeses Unicode normalisation please verify if other files using COMBINING DIAERESIS or other characters from the "Unicode Block 'Combining Diacritical Marks'" ( http://www.fileformat.info/info/unicode/block/combining_diacritical_marks/index.htm ) still exists in the database. best rgards reinhardt [[user:gangleri]] P.S. beside blocks Bug 3969: unicode compatibitity (tracking) I added blocks Bug 3985: character conversion (tracking)
*addendum* This report reminds me on Bug 3860: links generated with precombined characters show red despite the fact that the normalised links exist which is a duplicate of Bug 1527: *first* perform Unicode normalisation and check for existence of pages *after* the normalisation The reason why the file from the url is not "recognized" at http://de.wikipedia.org/wiki/Bild:Kohlenstoffnanor%C3%B6hre-Animation.gif might be the same. Because the file from the url "survived" the databases Unicode normalisation it is possible that other files using precombined Unicode characters still exist in the database. Many page titles at [[yi:]] used BiDi punctuation characters and different spellings ("tsvey-vovn" versus "vov+vov" etc.) in titles. It is very likly that the contributors used / are still using also precombined Unicode characters for (file) titles they uploded / are uploading. Other wiki's / languages where Unicode normalisation is involved might be affected as well. Identifying these is a general issue / relates to all wiki's. Bug 830: Commons rejects upload of filenames in Hindi might be "historical". Helpfull / usefill links from the original reporter are missing there. best regards reinhardt [[user:gangleri]]
Running a final check for remaining bad image names
Normalized remaining filenames last night.
