Webviews and written accents

Hi, I’m a novice with Corona SDK and i’m doing an App that need Webviews in some parts.

The problem is when I load a local html the letters with written accents are worng (With the html in utf-8).

I did a test with this html:

\<html\> \<head\> \<meta charset="UTF-8"\> \</head\> \<body\> \<h1\> HOLA \</h1\> \<p\> Andrés tiene una É, pero no una à ,á&nbsp;,À ,Á \</p\> \</body\> \</html\>

but the app show this:

And when is not local it shows written accents well. I tried to test this url: https://es.wikipedia.org/wiki/Acento_gr%C3%A1fico

How can I solve this?
