I can't look farther back than 4.104, but other Greek characters are not 
in that version. The FAQ addresses the question of Greek in the font:

Question: Why do the SIL Unicode Roman fonts have some Greek characters, 
but not all?

Answer: While it is true that the font includes some Greek characters, 
it is not intended to provide general support for the Greek language. 
Those Greek characters that were included were done so in order to 
support various (primarily linguistic) notational systems. If Greek 
language support is needed, the Galatia SIL and Gentium fonts are two 
available options.

(I'll add that you *may* be able to find a Greek font that harmonizes 
well with Charis at the Greek Font Society 
(http://www.greekfontsociety.gr/). Their fonts are good, and free.)

There's an address to send feature requests to on the Charis support 
page 
(http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&item_id=ComplexRomanFontFAQ#support), 
but it looks as if they aren't eager to add Greek support.

Libertine lacks the mkmk feature, which seems to be what you want. You 
can leave a feature request (see 
http://linuxlibertine.sourceforge.net/Libertine-EN.html#contribute), or 
if you know how to use a font editor get involved with that worthy 
project and add them yourself. It's Open Source!
