Example at http://gallery.ruwenzori.net/main.php/v/travel/SenegalPaulineVelo2008/20080228_113839_1454_SenegalPaulineVelo.jpg.html :

Look at the "IPTC: Keywords" field in the "Photo Properties" details. You'll notice that all tags are like "Transport/bicycle�;" with the "white interrogation mark on black hexagon" character just before the semicolon. All those tags were generated using Digikam.

Counter example at http://gallery.ruwenzori.net/main.php/v/misc/debugging/20080301_113020_1640_SenegalPaulineVelo-bis.jpg.html :

Look at the same field. The ones with the same problem were also generated using Digikam. The clean ones were added using exiv2 from the command line.

Several hypothesis are credible :
- Digikam produces perfectly good tags but Gallery 2 somehow misinterprets them. This seems invalidated by the clean tags produced by exiv2 which a reasonably trusted implementation.
- Digikam produces tags with an illegal non-printable character.

Note that this is not a browser character set problem : whether I force UTF-8 or ISO-8859-1 as the character encoding for rendering the page, the special character is always there.
