Not sure what you mean. Can you please elaborate on your question?

Usually its the encoding of the page. Try setting it to UTF-8, that might height..

The most common reason why this is happening, is that the content is coming from MS Word, and WORD is notorius for insert weird characters into text.

So the way to handle the text (even if it never came from word), is :

1. Copy the text and insert in to NOTEPAD (comes with Windows)

2. Then copy and text from NOTEPAD and insert it into your website. This will fix something like 95% of all the "?" symbols you see..

Also make sure you replace all the "angle quote" marks with "vertical" quote marks, and then all should be good

Hope this helps

Copy your content from the spreadsheet/text editor you use to notepad. Then copy that pasted content from notepad to your web page. This will prevent weird characters from displaying on your webpages.

If you meant asking on what character encoding should be used, try UTF-8.
