Hi
I'm using Zenphoto on a website, but I presently have the following problem : the month name of the image date is not encoded in the good charset, so the accentuated caracters don't display correctly (see on http://www.ocra-lyon.org/photos/Expositions/2007/Fevrier/15-Vernissage%20Mairie%209e/DSC00049.JPG.php for example).
I had gettext problems on the same server for another application so I had to rename the fr_FR to fr_FR.utf8@euro (the fr_FR locale wasn't present)
Have you any idea to solve it for Zenphoto ?
Did you note the warnings that setup.php gave you? http://www.ocra-lyon.org/photos/zp-core/setup.php. Specifically the one on mbstring which says that accented characters amy now work correctly?
