Thanks Nikos for the patch.

I notice that you made some extra changes. The 'extended' variant was removed, with the ASCII keyboard in the comment. It is easier to add patches for small changes at a time so that they are easy to identify in the version control system.

Could you please produce a new patch that keeps the extended variant? There are people using it. Also, if adding/removing layouts, we need to change some other files as well.

Indeed, there is duplication between 'basic' and 'polytonic' which could be resolved if we create a new 'hidden' variant with the common lines.

Therefore, pending the approval from Sergey,
a. You can create a new variant, let's say, 'bare_archaic' with those lines for archaic, etc characters, which are common to both 'basic' and (now) 'polytonic'.
Then, include 'bare_archaic' in both 'basic' and 'polytonic'. Finally, produce a patch that shows 'bare_archaic', the inclusion of 'bare_archaic', and the changes to 'polytonic'.
b. Or else make the changes in 'polytonic' without affecting the functionality of 'extended'.

Yes, I can see your point Simos. I must admit I made simple copy/paste changes in order to suit my personal needs, working a bit blindly on the way.

However, creating a new (even more, a secret one!) variant is out of my knowledge of these things, though definitely a cleaner solution as there are, indeed, a lot of overlapping characters. What I can do is restore the Extended variant and the ASCII keyboard in the comment should you wish, but that's all I'm afraid.

To create a new variant, you simply append the following

hidden partial alphanumeric_keys alternate_group
xkb_symbols "bare_extended" {

    key <AC05> { [ NoSymbol,       NoSymbol,          U03DD,          U03DC ] };//ϝϜ
    key <AC07> { [ NoSymbol,       NoSymbol,          U037C,          U03FE ] };//ͼϾ
    key <AC08> { [ NoSymbol,       NoSymbol,          U03DF,          U03DE ] };//ϟϞ
    key <AC09> { [ NoSymbol,       NoSymbol,          U03F2,          U03F9 ] };//ϲϹ
};

I show four lines, though there are more that are common and should be put in "bare_extended".

Then, for both 'basic' and 'polytonic' you include this 'bare_extended' variant, with

include "gr(bare_extended)"

That's it!

Simos's additions seem to be added to the current version of X.org (Fedora 23 lists libxkb-file-1.0.9-2), but with a small error that makes them invisible:

Line 148 of /usr/share/X11/xkb/symbols/gr should read 

include "gr(basic)" 

After making this change, I can access the additional characters.
