So what character do you get from Unicode (1025 dec), I hear you cry?  BTW, I almost suffered with diaeresis at the weekend – but I think that counts as oversharing …

On the way to the York- based Listener dinner the week before this puzzle appeared (aside: thank you Jane & John!), my wife and I stopped for a night in Lincoln, where we visited the Matryoshka Russian Doll shop  http://www.matryoshkarussiandolls.co.uk
Luckily I didn’t get started on a Listener Russian doll-based idea as, when this puzzle appeared the week after, Ifor clearly had the idea before me.  Phew …

I suspect at least one person is going to be kicking themselves for putting an E rather than an Ë character.  I think it’s something like (though my capital ‘SH’ isn’t very good!)

МATPËшKA
