[求助]近日用matlab(R2006)打开一需要的Model文件时，发现无法打开, 请勿发表与版面

各位高人，请教了！！！
当打开需要的Model文件时，出现：

Warning: Unable to load model file 'C:\Program Files\MATLAB\R2006a\QSS_TB\Library\qss_tb_library.mdl' due to the presence of characters that are not supported in the current character encoding setting 'GBK'. Either:
1) run "bdclose all; set_param(0,'CharacterEncoding', Enc)" where Enc is one of Shift_JIS, windows-1252, ISO-8859-1, then load the model, or
2) remove the unsupported characters. The first such character occurs on line 6666, byte offset 49.
??? Error loading Simulink model

请问谁知道这是什么意思啊？
我怎样才能打开这个模块？？？
到底是什么原因？
请高手指教，谢谢！！！

急用！！！！！！！！！!!!!!!
