disp(‘hello world’);

disp (‘hello world’);

[N/A]

a=((hello world))

Unexpected 'world' in parentheses. When creating a matrix, use square brackets [].

@Michael

That is incorrect. The function hello does not accept any input parameters, and does not return any outputs.

disp ('hello world');

hello world

Your apostrophes are wrong. How did you generate them? Here is your version:

disp (‘hello world’);

Invalid text character. Check for unsupported symbol, invisible character, or pasting of non-ASCII characters.

Error in connector.internal.fevalMatlab

Error in connector.internal.fevalJSON

You could also use double quotes: " "

This is a common problem that happens when people copy-paste code that's presented on websites that use prettytext formatting. I don't know if there are other issues with localization that could cause the same thing, but there are countless websites full of curly-quoted code. It's up to you to watch out for bad quotes, hyphens, and spaces.

It doesn't show up in the forum editor, but these invalid characters should be highlighted by your editor.
