Hi, I had a lot of problems to get the ZCatalog search work for international characters like german Umlauts (üäö etc.) I have read all the tips about setting the locale and so on, but nothing worked. Now I found a solution: I've added this line at the top of lib/python/SearchIndex/Splitter.c #define __XPG4_CHAR_CLASS__ just before the include of ctype.h. Then I recompiled Splitter.c (simply said make in the lib/python/SearchIndex directory) which recreates the shared library Splitter.so The define changes the behavior of utility functions like isalpha so that they work for the current local set. Before I restarted Zope I had set the current local with: setenv LANG de_DE.ISO8859-1 setenv LC_COLLATE de_DE.ISO8859-1 setenv LC_CTYPE de_DE.ISO8859-1 setenv LC_MESSAGES de_DE.ISO8859-1 setenv LC_MONETARY de_DE.ISO8859-1 setenv LC_NUMERIC de_DE.ISO8859-1 setenv LC_TIME de_DE.ISO8859-1 setenv LC_ALL de_DE.ISO8859-1 Then I restarted Zope and reindexed the ZCatalog and now I can find words with german Umlauts :-) I'm working on a Sun Sparc with Solaris 8 using gcc. Hope this tip helps Holger
