Why are you here?
You are probably trying to convert to Unicode/UTF-8 encoding but the change has created problems for you.
It's your lucky day! You've got the solution right here.
There are 3 things to remember:
1. Save the file in Unicode/UTF-8
2. Set the browser to show the file in Unicode/UTF-8
3. If you are using a database, set it to Unicode/UTF-8
How this is done depends on what software you are using.
You can choose what software you want instructions for in the menu on the right.
