Detecting utf8 encoding errors

While working with Froogle, the datafeed is constantly bugging me with encoding problems in so开发者_Python百科me article-descriptions.

The script, string and output is utf8 encoded, but I can't find the characters that cause the problem.

is there a way to detect troublesome characters?

Try using the htmlentities function for your string.

echo htmlentities($your_str, ENT_QUOTES);

And then use, html_entity_decode function to read back with utf8 as parameter.
