I use build_directory_field to change "foreign characters" to pure ASCII:
My full path is for example "Muut linkit/Sää/Merisää" and I have a field called Directory which has "Muut_linkit/Saa/Merisaa". What should I do to make Links SQL admin generate Directory entry automatically from Full_Name changing every space to _ and every umlauted character to non umlated like in my example?

This should be enough tr/åäöüÅÄÖÜ /aaouAAOU_/, but where to put it?

Lauri
