I set a=1234567890 but both script and console cannot display the number 1 and 4. So wired.

That is unusual, I don't think I've seen that behavior before. From your picture it looks like MATLAB can display the number 1 in certain circumstances (the line number, the title bar and tab for this file.) I wonder if it's a problem with the font that the Editor and Command Window are using. Try changing the "Code Tools" font in the preferences. If specifying a different font shows 1 and 4 in the Command Window and Editor correctly, could you post the name of the font(s) that you tried that did not work and the name of the font that did.
