Problem with displaying unicode symbols

[Alexey Karakulov]

When I do something like

ghci> let myPlot = layout1_title ^= "My title: йцукен" $
defaultLayout1 :: Layout1 () ()
ghci> renderableToWindow (toRenderable myPlot) 300 300

I got ugly text in picture, like "My title: 9FC:5=".

My system is linux with en_US.utf8 locale, so it shouldn't be encoding
problem.

It is encoding problem. Chars are somewhere truncated to bytes without
proper encoding

I suspect this has something to do with the "simple" API provided by
cairo for rendering text. I'll take a look at what's involved in the
more extensive text API in the next few days.
