how to add a utf-8 character to the title

[Brian Kidd]

hello,

this seems like a simple thing, but i've been unable to find anything  
in the archives and the documentation.

basically, i'd like to add a title that contains an accented  
character (unicode = 00e9). outside of lilypond the title would be:
Sinte' Intro

i can create the variable
accentE = #(ly:export (ly:wide-char->utf-8 #x00e9))

and then i've tried

i've tried:
\header{
  title = "Sint" \accentE " Intro"
}

however, this doesn't work. how can i concatenate these strings and  
utf-8 character to have the correct title?

thanks,
-brian
