Thanks, I'll have a look at it.
I do want to allow some chars so I'm trying to replace them
like this :
$post_text=str_replace(chr(146),"'",$post_text);
or
$post_text=str_replace("?","'",$post_text);
However, it seems that str_replace does not actually replace
the chars cause they still end up in the output.
any idea?

My suggestion finds high-bit characters (127-255), but you need to find
printable characters with the exception of \n and \r. So my suggestion won't
work for you, I'm afraid. Perhaps you want something like below?
$bad_string_flag = ! ctype_print(strtr($string, "\n\r", " "));
>From the docs, it seems that replacement string in strtr cannot be null for
correct operation, so I've used double blanks (or use any chars, e.g. "NR").
The strtr part feels a bit clumsy, but you might be able to find a better
way in "XVII. Character Type Functions" or "CLXI. String Functions" (PHP
Manual).
Kind regards,
