How to get a char as numeric hex with XSLT?

[Mikko Rahkonen <ra...@st.jyu.fi>]

Hi!

Is there any way to get the numeric hex value of a char with XSLT? 

I'm trying to avoid using JavaScript by generating GET-style HREFs Special
characters (other than a-z and 0-9) must be converted to # followed by the
hex value as string. For example http://foo?bar:baz should be defined as
http://foo?bar%3Abaz.

Thanks in advance.
