I'm really keen on testing 0.20_01 release. Will you please post to the 
mailing list if the release is testable. Because I also use a slightly 
modified version which support UTF-8 which you created prior to created 
a new version in trunk but for the moment it works great but I'm really 
looking forward to 0.20_01 devel.

Thanks for all your effort.

Best regards,

Marc
