Can anybody help me with a script to examine input on a web form and replace the following characters as follows.

Character Replace with
Ñ
ñ ñ
á á
é é
í í
ó ó
ú ú
& &
£ sterling
€ euros

All the vowels above are accented.

I would like to pass the contents of a text input box e.g. <input type="text" name="name"> into a function and have the function do the replacements (if any).

The replacement characters should be the numeric value (I need to space the value to prevent the browser rendering the characters)
ñ & # 241;
á & # 225;
é & # 233;
í & # 237;
ó & # 243;
ú & # 250;
