Recurring problem with symbols being replaced with “?”

[Prasad]

We have a recurring problem with symbols being replaced with “?”. Symbols used like © ψ ρ σ etc.,

ISSUE: when users use some special symbols like mentioned above and post data, ckeditor replacing them to '?' while saving to DB.

Editor is integrated into Php v5.5 with back end MySql 5.1

Please let us know if you need any more info.

You will be highly obliged if any help is provided to resolve ASAP.

Thanks

CKEditor is JavaScript application and has nothing to do with saving data. Please look for the problem in your backend.

We know that its nothing to do with save . But the output text coming out of CKEEditor into our HTML Form before saving having special characters being replaced with '?' . If we try the same special characters in normal HTM TextArea , its getting saved properly.

Are you getting this when switching to source mode and back? If not, please review code that gets data from editor (if this isn't CKEditor's getData() method which is used by default), if yes then please try reproducing this issue in default standalone editor without any custom plugins or code modifications as they might be responsible for this issue.
