UTF-8 With Signature or Without?

To KSW, it doesn't matter whether UTF-8 pages are signed or not
KSW works equally well with both signed UFT-8 pages (with BOM) and unsigned pages.

Where BOM counts
Although modern browsers recognize the encoding signature (BOM), older ones don't. This is why most page editors only save UTF-8 without signature. However, if you create a private KSW-enabled site (a "personal database"), or if your site is only accessible to a closed environment (like an intranet) where only new generation browsers are used, you may choose to use UTF-8 with BOM, as signed pages are certainly the best bet for the future.

Note. Older browsers actually display the signature bytes, at the very beginning of the page.
