Selected fonts are no longer displaying in LO 4.2.4.2 on OSX 10.9.4

I just discovered that while many of my fonts still appear in the font
menu, fonts such as Estrangello Edessa are no longer being displayed on
the screen in the document (English characters appear instead in a
variety of fonts.) Can anyone point me in the direction of what may be
happening. I saw some bugs related to fonts not appearing in the select
dropdown, but in this case the drop shows the font properly, but when
characters are entered they are entered they appear in a Latin font
though - not sure if this is something visited on me by an OS upgrade
or an LO upgrade....

At a guess, more font substitution issues - depending on the font type
(OTF seems to be a common culprit) and family font weights, LO appears
to carry out font substitution - this might be why you are seeing
different characters. There appears to be no workaround other than to
hope that OSX font support will someday be completely integrated
natively into LO - at present, this is not the case, at least, so far as
I understand the situation.
