          gate.util.BomStrippingInputStreamReader

All Implemented Interfaces:

Closeable, Readable

public class BomStrippingInputStreamReader
extends BufferedReader

StreamReader that removes the Unicode BOM, even when Sun/Oracle is too lazy to do so. Since a buffer is required, and since most of GATE was coded to use BufferedReaders around the InputStreamReader, this 'isa' BufferedReader. Note that there are differences in exception behaviour on the different InputStreamReader constructors, so this has to be careful to call the right one.
