PPI::Token::BOM(3) User Contributed Perl Documentation PPI::Token::BOM(3)NAME
PPI::Token::BOM - Tokens representing Unicode byte order marks
INHERITANCE
PPI::Token::BOM
isa PPI::Token
isa PPI::Element
DESCRIPTION
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.
METHODS
There are no additional methods beyond those provided by the parent PPI::Token and PPI::Element classes.
SUPPORT
See the support section in the main module
