INN 2.6.1 enforced more syntax checks on header fields at injection 
time, that is to say when a posting agent tries to inject an article in 
the news service.  The intent is to prevent malformed articles from 
reaching the news service.
I see that you quote an error from inews, an injecting agent that 
connects to nnrpd to POST articles.  Couldn't you try to use rnews 
instead?  rnews uses IHAVE to submit articles to innd, which performs 
less checks (as articles are considered already injected into the news 
service, and therefore should go on being propagated).

As Russ noted, odd characters are non-printable ones (and not non-ASCII 
chars).  8-bit printable chars are perfectly allowed (INN for instance 
copes with UTF-8 or latin1 encodings).
