Problems with special characters: á, é, í, ó, ú, ü, ñ


My website is UTF-8 encoded and my button has data-lang=“es”.
When I set a text with special characters like this: data-text="Radiomaratón Atrévete"
The button appears like this: Radiomaratón Atrévete
So, there are some problems with the special characters.
I’ve tried to change “á” with "á"but it gives me the same result.
What do I have to do to fix this???

Thanks in advance.


I just tried making a button that tweets you text and it works fine for me.
Do you have a link to the page having problems?
