this problem pertains not only to Zürich, but to 24000 other entries, so I guess that this is no option for me. And again, I am using the sqlite3 command line exe and can't compile a custom version. > Why would you ever want two % in a row? A % matches zero or more of > arbitrary characters.

Here, the problematic char is to be found in the *result set*, not in the query itself. How do you educate SQlite to return me "Sào Paulo" if only "Sao Paulo" is being entered? How do I know which character to substitute with a placeholder? Is it S%o Paulo to look for? Or Sa% Paulo? Or Sao P%ulo? I can't know this beforehand. These are just examples, i need a generic solution if possivble. All i can see so far is to build a table of all special characters ever used in the 24000 names of cities which make problems and remap them accordingly. -- Christophe Leske www.multimedial.de - i...@multimedial.de http://www.linkedin.com/in/multimedial Lessingstr. 5 - 40227 Duesseldorf - Germany +49(0)180102 - 06 60 02 96 // +49(0)177 249 70 31 This e-mail may contain confidential information.
