[exim] charset of “fail” messages

Hi all,

    When I do:

fail text "$home:/Nööö!!!"

… I get a fail message with:

/home/mortal:/N\303\266\303\266\303\266!!!

    This (with US-ASCII encoding) appears to be hard-coded into 
src/deliver.c … is there any motion in the direction of being able to 
specify an encoding for fail messages?

    Thank you!
