TEncoding.GetBufferEncoding

Attempt to guess the encoding of a buffer.

Declaration

Source position: sysencodingh.inc line 63

public class function TEncoding.GetBufferEncoding(

const Buffer: TBytes;

var AEncoding: TEncoding

):Integer; overload; class function TEncoding.GetBufferEncoding(

const Buffer: TBytes;

var AEncoding: TEncoding;

ADefaultEncoding: TEncoding

):Integer; overload;

GetBufferEncoding checks the BOM marker of an array of bytes Buffer, and returns the found encoding in AEncoding. Only the TEncoding.BigEndianUnicode TEncoding.Unicode and TEncoding.UTF8 encodings will be tried.

If AEncoding is non-Nil on entry, it will be used to check the BOM marker with. No other encoding will be tried in that case.

If ADefaultEncoding is specified, it will be returned in case no match was found.

The function returns the number of bytes in the BOM Marker.

TEncoding.BigEndianUnicode		Big-endian Unicode (UTF16BE) encoding instance.
TEncoding.Unicode		UTF16 encoding instance.
TEncoding.UTF8		UTF8 encoding instance.
TEncoding.GetPreamble		Return the BOM Marker used by the encoding.
