Problem with non-printable characters

Hello!

I've got a problem with some non-printable characters in a UTF-8 HTML document, specifically \u001f and \u001e.

I'm retrieving some data in JSON format, and using json_decode to convert the data into a PHP object.

It seems to be working fine, except those couple of characters. What's the best way to handle this?

I also have the ability to manipulate the data before it's packaged as a JSON string.

Thanks!

Those are the UTF-8 way of representing the 'RS' (0x1e) and 'US' (0x1f) ASCII control codes.  Those used to be used as separators in data streams.  If you have no use for them, you can just dump them.

I wasn't sure how to strip them, but figured it out with your help. Thank you.

str_replace( array( "\x1e", "\x1f" ), '', $string )
