I cannot save matlab editor, the .m file.

Hi,

When I save the .m file, it warning that " The matlab editor cannot use US-ASCII encoding to save the file, please use UTF-8 encoding to save the file ". Am I missing some kind of file? What do I need to do? The computer I use is MAC, the matlab version is R0221a.

Look forward to your reply!

Use Save As to save the file. The saving box that comes up will have a menu that allows you to select the format of the file to save as. Make sure that UTF8 is selected, not ISO-8896-1 and not "all .m files"

I guess that you must have used some special characters like accents, have you copy-pasted something into the editor?

[Walter Roberson]

Right, you can get this message if your file includes any character whose Unicode code is outside the range 0 to 255.

I can’t use it after I clean the computer. I suspect that some files have been deleted automatically.

You might want to check what your locale settings are

feature('locale')

and see if any of this is of use:

My understanding was that this should be utf8 in that version/env, but maybe yours is set to us-ascii for some reason.

This might also be of help.
