[wp-polyglots] Character encoding?

[Lloyd Budd]

Posts like http://climbtothestars.org/archives/2007/01/29/invalid-argument-supplied-for-foreach-in-wp-capabilitiesphp-case-cracked/
and the regular questions on the forums is a near continuous reminder
that WordPress needs a comprehensive solution to character encoding.

http://trac.wordpress.org/ticket/3517 seems to have good context, but
it is not an area that I have strong technical knowledge. I am about
smart enough to read
http://www.joelonsoftware.com/articles/Unicode.html , but that is
about it.

Does someone on these lists have the expertise to make these problems history?
