Why fonts available with X and not with KDE/GNOME ?

[Hervé Piedvache <footcow@noos.fr>]

Hi,

I have a trouble with fonts ... I can see some fonts under X ... with xfontsel 
for example ... or  with this command :

$ xlsfonts | grep -i adobe | grep 'iso8859-15'
-adobe-itc avant garde gothic-book-o-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc avant garde gothic-book-r-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc avant garde gothic-demi-o-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc avant garde gothic-demi-r-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc bookman-demi-i-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc bookman-demi-r-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc bookman-light-i-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc bookman-light-r-normal--0-0-0-0-p-0-iso8859-15
-adobe-itc zapf chancery-medium-i-normal--0-0-0-0-p-0-iso8859-15

But under KDE or GNOME ... with the for example the font selector of KDE; or 
inside applications like Kate ... I never see those fonts ... called for 
example itc zapf chancery [adobe] on other system I have ...

Does someone have any idea to solve this trouble ?

Thanks per advance ! ;o)
