Invalid characters for MOSS 2007

Recently there was some strange issues surfacing, which my team in the project believe is due to some invalid characters being used in the filename of the content pages or document filenames. Some of the symptoms observed are:

1.       For WCM/ECM, the Page Editing Toolbar sometimes disappears.

2.       User unable to perform upload multiple files where there’s invalid character in the filename.

For the full list of invalid characters for site names, folder names, server names, and file names, refer to the MS KB905231 at http://support.microsoft.com/kb/905231.
