[Seaside] WAResponce, XML response and BOM

[Martin Kobetic]

Yup, our http server seems to be what you call "encoded" server adapter. So entering the BOM mark already encoded in utf-8 results in it being re-encoded yet again in utf-8. To achieve the desired effect the response should be built as:

Seaside.WAResponse new
    contentType: 'text/xml;charset=utf-8';
    nextPut: 16rFEFF asCharacter;
    nextPutAll: chart xmlString;
    yourself

Let the adapter do the utf-8 encoding of the BOM mark character (U+FEFF).
