Detailed Description:
Hi,
in some cases (e.g. SEO reasons) it is nessacary to keep indexed urls consistent
and permanent. So even an old url that may be not that elegant should be
preserved. For exmaple URLs with douoble hyphens. LISE classifies custom URLs
with double hyphens as invalid and does not accept it. In my case, that means
over 100 URLs would have to be reindexed or redirected. Perhaps LISE could be a
bit more generous here. After all, a hyphen itself isn't an invalid character.
