Accented subject characters

[kf-grb@xxxxxxxxxxx]

I use a short bash script to have mixminion-0.0.8alpha2
send/post a prepared text file. Example:

#!/bin/bash
# Use quotes for multiword headers: Re: soandso "Re: soandso"
#--recommended  DONTWORK
#--X-No-Archive=Yes  DONTWORK
#--subject="Re: sömésûbjèct"  DONTWORK
/home/.../mixmin/bin/mixminion send \
-t mail2news-20070308-alt.test@xxxxxxxxxxxxxxxx \
-P "*3,banana" \
--input=/home/.../mixmin/sourcefile.txt \
--subject="Re: somesubject" \
--references="" \
--in-reply-to="" 


I get barked at if the subject line contains accented 
characters even if the whole string is enclosed in
double quotes. Is there a workaround for this (backslash
escape doesn't seem to cut it)?

Also, in the wishlist department, I would far prefer 

- having all disclaimers in X-headers with a view to keeping 
  the readability/threadability as clean as possible
- some form of the --header syntax used in mixmaster that
  allows assorted X-headers to be used/created
- the [Anon] prepended to 'From' appended instead so as
  to support sender-based sortability.

Finally, does anyone have some idea as to the date when
usenet posting will/might become functional?  I don't think
I can use SURBS in conjunction with m2n...

 
Thanks very much!
