Well, there is this uri-escape function in xpath 2.0:
	http://www.w3.org/TR/xquery-operators/#func-escape-uri
sadly, though, it only came into existence two months ago (Jun 17).

It would be enough since then "translate(escape-uri(str, true), '%', '=')"
would give me a suitable string for RFC822 headers when wrapped with
=?utf-8?Q?...?=

However, this function doesn't explain very clearly what is done for
non-ascii characters; are they represented by a utf-8 stream? I assume so
since the examples they give are compatible ascii and yet they must work on
all of unicode... I have sent a clarification to w3c regarding this.

Portability is an issue. :-( The pages are all xml with the intention that
then browsers can use different xsl to format them to user taste.

Grrr. Maybe I will make a patch for libxslt1 and just let the IE users eat
it for now.
