0x82358738 is the last character ij the font. This is a real problem. 
0x82358739 do not have glyph and it display as ? which is not a problem.

according to the table Brian Yuan gave me 
0x82358738 in GB18030 map to unicode 4DB5
and 
0x82358739 in GB18030 map to unicode 4DB6

However, 4DB6 is undefined in Unicode 3.0

the bug is we clear up the font information for non han characters, but I start 
from the wrong position, I clear from 4DB5 and above while I should clear from 
4DB6 and above.
