How to write UTF-16 with BOM in little endian Von: Jean-Marc Autexier <[email protected]> Datum: Samst

Hi,

I must write UTF-16 files, with byte order mark (BOM) in little endian (jdk
1.4.2).

According to java.nio.charset, UTF-16LE and UTF-16BE don't use BOM, UTF-16
does (as defined in Unicode and XML standards).

UTF-16 can read big and little endian, but can only write big endian (see
below). Why?

From http://java.sun.com/j2se/1.4.2/docs/api/java/nio/charset/Charset.html

- When decoding, the UTF-16BE and UTF-16LE charsets ignore byte-order marks;
- when encoding, they do not write byte-order marks.
- When decoding, the UTF-16 charset interprets a byte-order mark to indicate
the byte order of the stream but defaults to big-endian if there is no
byte-order mark; when encoding, it uses big-endian byte order and writes a
big-endian byte-order mark.

UnicodeLittle and UnicodeLittleUnmarked should give you what you want.

Thanks Roedy, I finally found it out by myself and was just about to post
the answer.
This solve my problem, but I'm curious to know why it is not supported in
java.nio?
See http://java.sun.com/j2se/1.4.2/docs/guide/intl/encoding.doc.html,
UnicodeLittle and UnicodeBig are only supported in java.io.
