Problem with characters after formatting

I have recently formatted my computer and I've noticed a weird thing for the first time here on an article.. the problem is: src=”test.jpg” by the meaning i think that ” should be a-" but this is not what i'm seeing.. same thing happens to me with nicknames in the messenger.. any help?? thanks..

It might just be your browser, try a different one (and post which you're using)

When your talking about the articles, The strange characters appear because the person wrote it in a word processing app like MS wordpad then copy and pasted it to the website. The problem is word apps use hidden formatting codes and web browsers can't decode them.
