There are two ways to solve this problem.
1. Change a locale of OS to the country where a model is made. To change the locale on Windows machine:
Select Start -> Control Panel -> Clock, Language, and Region -> Regional and Language.
Open Formats tab.
Select a target locale from the Format: drop-down list.
2. Delete the characters not supported in the Character Encoding.
This is a way to delete the characters from a model.
(1) Remember error message "・・・Line 123 , 45 bytes" when opening Simulink mode.
(2) Open Simulink model by MATLAB editor, and look for Line 123, 45 bytes. If you find specific character, delete it and save it as ".mdl" file.
(3) Open the model made by (2).
Do the procedure (1)-(3) until all the error are resolved.
Finally, open the model again by MATLAB editor. Find character "SavedCharacterEncoding", and change the value as following, and save it.
SavedCharacterEncoding "Shift_JIS"
