Chinese garbled solution for IPhone Zbar Library--Recompile LIBZBAR.A

Zbar has a problem, for the Chinese two-dimensional code support often appear garbled. Zbar default Support Shif-jis, UTF-8, iso8859-1, but do not support GB18030, and many of the generated two-dimensional code is GB18030 (or GBK, GB2312), so the Zbar decoded out of the direct garbled

This change is actually very simple, only need to modify a file on it, see the following code.
