如何修改脚本打印的字符串？

Question

I'm having problems with wordpress mishandling accented characters, or maybe the problem is with some plugin. Whichever the case I need to "translate" some strings, removing accents which i do with:

  $value = strtr($value, $trans);

I really need to change this string which renders the user's location but it's printed with a script so I have no idea how to do it:

<script language="javascript"> document.write('' + geoip_city() +''); </script>

Is there a way to assign it's result to a php value beforehand or something? Maybe removing the accents with a script. I really need to modify it, how could I manage to do it? Thanks

The only way I could see this happening is by using output buffering, see

http://php.net/manual/en/function.ob-start.php

and

http://www.php.net/manual/en/function.ob-get-clean.php

Though if at all possible I would avoid using this, it's not exactly best practice. See if the function in question takes any arguments to return the data rather than print it and otherwise duplicate the function and make the changes you need to it.
