Vim Keybindings in Characters from Different Languages

When I use the Vim keybindings with latin characters everything works fine, but when I change my keyboard layout to a different layout then non of the Vim keybindings work.

The same thing happens to Vim also, so I remapped all the letters (uppercase too) like this

   {
        "before": ["q"],
        "after": []
    },
    {
        "before": [";"],
        "after": ["Q"]
    },
    {
        "before": ["ς"],
        "after": ["W"]
    },
    {
        "before": ["Ε"],
        "after": ["E"]
    },
    {
        "before": ["Ρ"],
        "after": ["R"]
    },
    {
        "before": ["Τ"],
        "after": ["T"]
    },

Now with that the keybindings with single keys work fine but those that need two keys don't. For example δ is mapped to d, so when you press δδ it should delete the line like dd does. But it doesn't. In order to do that I should make the following remap, with which it works

    {
        "before": ["δ", "δ"],
        "after": ["d", "d"]
    }

The second step is not necessary for Vim and also it is not a viable option to remap everything like this. Furthermore it shouldn't be needed given that all the keys are already mapped.

Do I miss something? Is there a better way to achieve this? At the moment it seems to me like a bug or perhaps a missing feature.

Also thank you all devs for the great work you did in this extension!

Use the reported Greek-layout reproduction and the δδ versus dd behavior as the starting case. Trace how multi-key Vim commands are matched after remappings, then verify whether mapped single keys participate in sequences. Done means δδ performs the same line deletion as dd without requiring every two-key mapping to be listed.
