79273 - add GB18030 4 byte conversion support to unicode conversion engine

Status: RESOLVED FIXED

(Core :: Internationalization, defect)

Description

[Frank Tang]

This is a sup part of fixing 

Basically, GB18030 is a 1,2,4 byte encoding
the 4 byte part encode character in the following range
byte 1: 0x81-0xfe
byte 2: 0x30-0x39
byte 3: 0x81-0xfe
byte 4: 0x30-0x39
This 4 byte form a 126 x 10 x 126 x 10 linear space
and the unicode which defined in Unicode 3.0 and do not have mapping in GBK get 
map to this space in 149 range. 

We need to add functionality to our unicode conversion engine to convert this 4 
byte range to a linear space and back

Frank, do you have a table for GB18030?  If you have it, please attach it. 
QA cannot verify this if we do not have table.

We do not have fonts for Windows, so we cannot verify this.
I change QA contact to the reporter.
