Comment:

 Ivan,

 integer->char is already unicode aware.

 {{{
 $ csi -e '(write (integer->char #x3bb))'
 \u3bb
 }}}

 What is not unicode aware is converting this character to a string using
 (string c) or (make-string 1 c). However, you can use the system procedure
 ##sys#char->utf8-string:

 {{{
 csi -p '(##sys#char->utf8-string (integer->char #x3bb))'
 λ
 }}}

 It is trivial to modify html-entity-unicode-chars to call this instead of
 core make-string, which will not require the utf8 egg.  In fact I did a
 similar thing in the 'ssax' egg so that numeric entities are parsed into
 utf8 sequences without requiring the utf8 egg.

 Speaking of which, shouldn't this be filed against the ssax egg and not
 against sxml-transforms?
