[users-biblio] Use of Greek letters in bibliographic entries

[Simon Gant]

Hi,
I have a few articles I'll like to reference in my document which have Greek
letters in their titles. I've tried just copy-pasting the Greek from
OoWriter into the Biibliography Database but it gives the error: "Error
inserting the new record: invalid value for column in 'Title'". Is there a
way of using non-english letters and also sub/subscript letters, e.g.
chemical formulae, into Bibliographic entries?
Cheers, Simon
