html - Why my page cannot display é, instead, showing ??

Question

I have set page encoding to UTF-8 in HTML:

meta http-equiv="content-type" content="application/xhtml+xml; charset=UTF-8"

and in HTTP header, I have:

Content-Type    text/html; charset=UTF-8

Why isn't the é shown correctly?

---

Update:
The data containing the é is crawled from the Internet; the crawler is written in Microsoft .Net. I used MySQL .Net Connector to connect MySQL.

The page to display the é is written in PHP.

You need to add much more information, but a ? is usually a sign for a ISO-8859-1 character in data that is treated as UTF-8.

It comes either from

• The source file claiming to be UTF-8, but actually being saved as ISO-8859-1/Windows-8252 - check your file encoding in your editor or IDE

• A database connection that uses ISO-8859-1 even though the database tables are UTF-8
