This is bogus! While encodeURIComponent() operates on utf-8 escape() 
uses iso-8859-1. Both functions convert the local chracter set of the 
page to their "native" charsets. Their decode conterparts do likewise in 
the other direction.

This means we must not use escape() exceot for iso-8859-1. This also 
means we can safely use a encodeURIComponent/decodeURIComponent() pair 
within Javascript as the functions do the necessary conversions 
themselves. When it comes to ineratction with PHP the PHP script has to 
take care to do the right encoding on the server side, which isn't very 
hard to do.
