Another bit of good news is that these three expanded DejaVu font sets
each include a glyph for the  Ľokina <U+02BB>.

This is important for some languages of Oceania (Tongan and Samoan).
I've managed to get a Samoan L10n effort started and knowing that the
 Ľokina glyph will be properly presented is reassuring.
