> Hello,

> comparisons when searching for keywords.
> 1. The digiKam handbook says "searches are case insensitive".
> Well, doesn't seem to be the case in my environment (digiKam 1.2.0,
> Linux OpenSuSE 11.3 with KDE 4) with non US ASCII characters.
> I have several pictures with captions containing the word "église"
> (for non French readers, église is a church). E.g. picture 1 is
> titled "Petite église rouge", and picture 2 is titled "Église à
> vendre". (With an uppercase É because all my titles are
> capitalised.)
> Now, if I type (in the words search input field) the word "église",
> I get picture 1 but not picture 2. And if I type "Église", I get
> picture 2 but not picture 1. Clearly a case sensitive match,
> concerning only the ISO Latin characters (typing "éGLISE" finds
> picture 1 too, and "ÉGLISE" finds picture 2).
> I suspect it could be a problem with non ASCII characters encoding.
> My desktop environment is set to French, ISO-8859-1 charset.
> How digiKam internally encodes its text strings ? UTF-8 maybe ?
> This could possibly explain a mismatch.
> Has anyone already seen such an issue, and what could be the best
> way to walk around ? Is there a way to tell digiKam about user input
> encoding, us-ascii, iso-8859-x, utf-8 ? Or is it shadowed by the
> X11/Qt/KDE layers ?
> 2. Another question related to strings match, just because I'm
> curious :-)
> In the digiKam configuration window, folder "Miscellaneous",
> there's a configuration parameter named "String comparison type",
> with a selection menu proposing two options, Natural or Normal.
> I couldn't find anything about that in the handbook. What is a
> "Normal" comparison type, and a "Natural" comparison type ?

SHIFT+F1 over the drop-down menu doesn't help ?
