PPI::Token::BOM - Tokens representing Unicode byte order marks
This is a special token in that it can only occur at the beginning of documents. If a BOM byte mark occurs elsewhere in a file, it should be treated as PPI::Token::Whitespace. We recognize the byte order marks identified at this URL: http://www.unicode.org/faq/utf_bom.html#BOM
UTF-32, big-endian 00 00 FE FF
UTF-32, little-endian FF FE 00 00
UTF-16, big-endian FE FF
UTF-16, little-endian FF FE
UTF-8 EF BB BF
Note that as of this writing, PPI only has support for UTF-8 (namely, in POD and strings) and no support for UTF-16 or UTF-32. We support the BOMs of the latter two for completeness only.
The BOM is considered non-significant, like white space.
There are no additional methods beyond those provided by the parent PPI::Token and PPI::Element classes.
