Remove Diamond Characters
While having a recent problem, an issue encountered on a webpage where diamond sign was appearing something like � and in actual it was a hyphen sign or dash ( – ).
To get rid of such cases, it is only advisable to check out that the document you’re copying the text from, is in right format, and if not, then may be you should convert the document into proper format, otherwise you will have to remove all the special characters, like hyphen, dashes, pipe signs etc. yourself and add them again by simply overwriting the right characters.
Hope this helps.
