JabRef insertion to LyX fails with accented character

[Rich Shepard]

Now I've learned how to insert accented characters using my keyboard I
corrected the lead author's name in JabRef from Antao to Antão. This morning
when I tried compiling the document with that citation it failed to find the
non-accented record in the .bib.

I deleted the ??.?? citation and tried to push the accented one to the
document. It keeps failing; the citation is still ??.??. I'm really
surprised that this happens.

Is this a LyX or JabRef issue?

TIA,

Rich
