Don't know for sure...quad = 4byte = 8 bits 4 bytes = int in java./Kaj

As far as I can see from googling, a quadbyte is a unit of four bytes.

So is there anything special that we need to do in Java to hadle a Quadbyte characters? If so can some one tell me how?TIA,C

If you are trying to ask if Java has a built-in data type for this, then the answer is no. But it's four bytes? How complicated can it be? byte[4] is one possibility.

Another option is to use an int to store the four bytes.

@OP. Why do you want to do this?

We are going to modify our application for China. We are going to get all the chinese text in Quadbyte characters instead of double byte.

Java 5.0 Improves Font/Unicode Support

One of the difficulties in using Chinese with Java has been the old font properties

method Java uses to map the physical fonts on the system to the logical fonts it uses.

To display Chinese, either you had to edit the font.properties file on the host system

(not something you want to ask a user to do) or have the program find a physical font

that supports Chinese on the system and then use that. With Java 5.0, Java will now

automatically find and use fonts that support the display of whatever writing system

you抮e using, as long as that font is installed on your computer. As of 5.0, Java

character handling is now based on version 4.0 of the Unicode standard. Unicode

v4.0 includes 揅JK Unified Ideographs Extension B?and other additions of CJK

characters not found in Unicode v3.0.

So is that UTF-32 or what? Your problem isn't going to be dealing with four bytes at a time, that's trivial, it's going to be converting them to Unicode.

Java 1.5 (5.0) has added support for supplementary characters in Unicode. You will find that the Character, String, and BreakIterators have been updated to handle "quadbytes" as you call them...I assume you mean supplementary characters or surrogate pairs.

These characters are represented as surrogate pairs in the Java environment.
