[edit] What happens

From Wikitravel Shared:Travellers' pub#Help with Image

Image:Nørrebrogade.jpg's thumbnail is not shown because of following errors.

Error creating thumbnail: convert: unable to open image `/var/www/html/wikitravel.org/upload/shared/a/a5/Nrrebrogade.jpg': No such file or directory.
convert: missing an image filename `/var/www/html/wikitravel.org/upload/shared/thumb/a/a5/Nrrebrogade.jpg/800px-Nrrebrogade.jpg'.

[edit] When it happens

If filename contains "ø", "ö", "ä", "ç", "å".

A few other accented letters are okay, e.g. Image:Aerial view and ferryboat, Îles-de-la-Madeleine (Magdalen Island), Québec.jpg

This appears to be a new bug introduced in an upgrade sometime in late 2008. (?) Jpatokal 04:11, 2 July 2009 (EDT)

Maybe, the problem is related to upgrade or something like server components change. And this problem occurs with not only letters with diacritical mark, but also any other non-Latin alphabet like Chinese, Hangul, Japanese, etc. -- Tatata 05:54, 2 July 2009 (EDT)

The similar thumbnail error, maybe the same, is found at Tech:Cache not clearing after editing#Thumbnails show up as gray box. It was reported by User:Shoestring at 09:17, 2 October 2008 (EDT). -- Tatata 12:15, 2 July 2009 (EDT)

I think is an unrelated cache issue, caused by the thumbnail generation being too slow, and thumbnails eventually come up if you just wait/purge enough. The special character issue, on the other hand, is permanent. Jpatokal 01:22, 3 July 2009 (EDT)

The thumbnail error reported by User:Shoestring is not a cache issue but a special character issue, since his file name includes "Mahébourg"[1]. It means that the special character issue has come up in September 2008. I guess that the special character issue is related to the new server migration or the fix of image generation problem when a cache issue occurred. -- Tatata 12:58, 15 July 2009 (EDT)

[edit] What should happen

Thumbnail should be shown.

[edit] How to fix it

Wikitravel's program ignores special characters in file name.

Wikitravel (language versions and Shared)

Original file name	File name in error message	Error message
Bus terminal, Mahébourg, Mauritius.JPG	Bus_terminal,_Mahbourg,_Mauritius.JPG	サムネイルの作成中にエラーが発生しました: convert: unable to open image `/var/www/wikitravel/upload/shared//7/74/Bus_terminal,_Mahbourg,_Mauritius.JPG': No such file or directory. convert: missing an image filename `/var/www/wikitravel/upload/shared//thumb/7/74/Bus_terminal,_Mahbourg,_Mauritius.JPG/160px-Bus_terminal,_Mahbourg,_Mauritius.JPG'.

Wikimedia Commons' program can handle special characters in file name.

I think that Wikitravel's program need to do urlencode for file name just like Wikimedia Commons do. -- Tatata 13:53, 15 July 2009 (EDT)
