运行一个程序时出现以下错误提示：
??? Unable to load model file 'D:\Backup\我的文档\MATLAB\xhsy\chou_shi.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 windows-1252, ISO-8859-1,
then load the model, or
2) remove the unsupported characters. The first such character occurs on line 140, byte offset 21.

Error in ==> snsmap at 147
