Class UnicodeInputStream

java.lang.Object

java.io.InputStream

net.anotheria.util.io.UnicodeInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class UnicodeInputStream
extends InputStream

This inputstream will recognize unicode BOM marks and will skip bytes if getEncoding() method is called before any of the read(...) methods. Usage pattern: String enc = "ISO-8859-1"; // or NULL to use systemdefault FileInputStream fis = new FileInputStream(file); UnicodeInputStream uin = new UnicodeInputStream(fis, enc); enc = uin.getEncoding(); // check and skip possible BOM bytes InputStreamReader in; if (enc == null) in = new InputStreamReader(uin); else in = new InputStreamReader(uin, enc);
