enum wxBOM

Constants representing various BOM types.

BOM is an abbreviation for "Byte Order Mark", a special Unicode character which may be inserted into the beginning of a text stream to indicate its encoding.

Since:

2.9.3

Enumerator:

wxBOM_Unknown	Unknown BOM. This is returned if BOM presence couldn't be determined and normally happens because not enough bytes of input have been analysed.
wxBOM_None	No BOM. The stream doesn't contain BOM character at all.
wxBOM_UTF32BE	UTF-32 big endian BOM. The stream is encoded in big endian variant of UTF-32.
wxBOM_UTF32LE	UTF-32 little endian BOM. The stream is encoded in little endian variant of UTF-32.
wxBOM_UTF16BE	UTF-16 big endian BOM. The stream is encoded in big endian variant of UTF-16.
wxBOM_UTF16LE	UTF-16 little endian BOM. The stream is encoded in little endian variant of UTF-16.
wxBOM_UTF8	UTF-8 BOM. The stream is encoded in UTF-8. Notice that contrary to a popular belief, it's perfectly possible and, n fact, common under Microsoft Windows systems, to have a BOM in an UTF-8 stream: while it's not used to indicate the endianness of UTF-8 stream (as it's byte-oriented), the BOM can still be useful just as an unambiguous indicator of UTF-8 being used.
