* Unit test for BOM in JSP classic (standard) syntax.
*
* Each of the JSP pages accessed by this test is preceded by a BOM from
* which the JSP container derives the page encoding:
*
* Page Page Encoding Bytes
* UTF-16BE.jsp UTF-16, big-endian FE FF
* UTF-16LE.jsp UTF-16, little-endian FF FE
* UTF-8.jsp UTF-8 EF BB BF
*
* This test enforces that the BOM does not appear in the generated page
* output, and that the charset component of the Content-Type response header
* matches the charset identified by the BOM.
