MATLAB: Am I unable to use Korean block names and path names in Simulink 7.1 (R2008a)

errorkoreanmodelnamepathsave_systemSimulink Control Design

I implement the following steps in Simulink 7.1 (R2008a)
1. Open simulink new-model editor. 
2. Drag and drop some block into the model. 
3. Re-name the block in Korean and Save the model. 
Simulink complains that Korean characters cannot be saved:
 
??? Error using ==> save_system
 
If  I execute the following commands
 
bdclose all; set_param(0, 'CharacterEncoding', 'ISO-8859-1')
 
I can save mdl file with Korean named block.

This enhancement has been incorporated in Release 2011b (R2011b).  For previous product releases, read below for any possible workarounds: 
 
There is a limitation in Simulink 7.1 (R2008a) in the way that non ISO-8859-1, US-ASCII, Windows-1252, or Shift-JIS, character encodings are saved or loaded for the first time. Attempting to save or load such a model will cause an error.
As a workaround, execute the following at the MATLAB command prompt, and then save the model.
 
load_system('simulink');
feature('MultibyteCharSetChecking',0);
