[EMBOSS] Illegal character warnings in uniprot

[simon andrews (BI)]

Our regular update of uniprot threw up some warnings when we updated
over the weekend.  It's not clear from the error which line in the entry
is problematic, but it doesn't seem to have caused any major problems
and I can still retrieve and query the sequences from the indices
created.

We're still on EMBOSS v4 (I know I should update - but it works for what
we use it for!).  Is this something which is fixed in later versions or
is it something new in uniprot itself?

I'll paste in a couple of the 174 warnings I got.

Cheers

Simon.
