Hello,

We are in the process of switching everything to UTF8, which includes converting our MySQL databases to UTF-8, it's content, and converting our templates so that they use html entities instead. So our source code is still in iso.

We are thinking about overloading the string function to use mbstring functions instead, so that functions like trim, strpos, strlen, etc work will our UTF8 strings.

The problem is that Zend Framework is also using string functions. I am not sure how such an overload to use mbstring functions instead might impact Zend Framework? Will Zend Framework still work the same if it's using mbstring functions instead?

If anyone with similar experience could share some knowledge with us, I would appreciate.
