QSLUGIFY: clean a string
^^^^^^^^^^^^^^^^^^^^^^^^
Convert a string to only use alphanumerical characters and '-'. Characters with accent will be replaced without the accent.
Non alphanumerical characters are stripped off. Spaces are replaced by '-'. All characters are lowercase.
Example::
10.sql = SELECT QSLUGIFY('abcd ABCD ae.ä.oe.ö.ue.ü z[]{}()<>.,?Z')
Output::
abcd-abcd-ae-a-oe-o-ue-u-z-z
